into libc. This reduces the size of every dynamically linked
executable by 248 bytes, and it reduces the size of static executables
by a lesser amount. It also eliminates some global namespace
pollution.
With this change in place, the source for dlfcn.h should probably
be moved to "/usr/src/include". I'll save that for another day.
Compatibility note: Programs which use dlopen, if compiled on
systems with this change, will not run on systems with a libc from
prior to this change. Very few programs use dlopen, so I think
that is OK.
Document `make readmes'. This is getting old, and the intent is to
stop questions regarding it; however, I have a suspicion documenting it
will work counter to ending questions about it and am mentally prepared
to see it go-ooooooooo.......
waslocked = TRUE. This change may fix lockmgr panic in umapfs/nullfs.

I've worked to enhance the connect() patches.
I've just tested this with the Linux JDK appletviewer on an applet
that does a lot of connects, and it works as well as during my
previous tests.
The connect() patch is now a merge between my older patch and the
OpenBSD stuff. It ensures that any async error is returned by
connect() instead of getsockopt(SOL_SOCKET, SO_ERROR) as reasonnable
systems do.
There are also minor patches to implement IPPROTO_TCP for
get/setsocktopt(). These are also tested (with Linux Apache).

I would appreciate any feedback regarding these changes, as they'd
be very useful in 2.2.6.

urgent need is when you run sh around a program that intentionally
uses SIGQUIT/SIGINT for asynchronous events, i.e. $EDITOR started from
system(2), like many mailers do. This fixes PR bin/1206 and possibly
bin/4241.
The solution committed has been tested for a large number of possible
cases (see recent discussion on cvs-committers). I completed a make
world, made sure 'make world' is interruptable and used the changed
/bin/sh as a login shell all day, including job control and using
SIGQUIT-catching programs (to write this message :-).

Probably the same will have to be done for the LOGIN_CAP_AUTH case.

3) When appropriate, set the PG_A or PG_M bits a-priori to both avoid some
processor errata, and to minimize redundant processor updating of page
tables.
4) Modify pmap_protect so that it can only remove permissions (as it
originally supported.) The additional capability is not needed.

Realtime priority has to be restricted for reasons which should be
obvious. However, for idle priority, there is a potential for
system deadlock if an idleprio process gains a lock on a resource
that other processes need (and the idleprio process can't run
due to a CPU-bound normal process). Fix me! XXX
