aa695ee90e Backout unblocking of signal if no threads can currently handle it. 
The check for pending signal after direct invocation of signal handler
is sufficient.

d21c14576e Delay unblocking signal and restoring process signal mask until the 
thread signal mask has been updated to avoid stack overflow during signal
bursts.

Don't block signal forever if no threads can currently handle signal.

Blocking on the malloc spinlock would cause the select timeout to be lost.

4c5083a81c Provide more POSIX-complaint ttyname_r(3) interface[1], which is slightly 
different from what has been offered in libc_r (the one spotted in the
original PR which is found in libthr has already been removed by David's
commit, which is rev. 1.44 of lib/libthr/thread/thr_private.h):
	- Use POSIX standard prototype for ttyname_r, which is,
		int ttyname_r(int, char *, size_t);
	  Instead of:
	  	char *ttyname_r(int, char *, size_t);
	  This is to conform IEEE Std 1003.1, 2004 Edition [1].
	- Since we need to use standard errno for return code, include
	  errno.h in ttyname.c
	- Update ttyname(3) implementation according to reflect the API
	  change.
	- Document new ttyname_r(3) behavior
	- Since we already make use of a thread local storage for
	  ttyname(3), remove the BUGS section.
	- Remove conflicting ttyname_r related declarations found in libc_r.

Hopefully this change should not have changed the API/ABI, as the ttyname_r
symbol was never introduced before the last unistd.h change which happens a
couple of days before.

674bc2cc3f Change libkse back to libpthread and make it the default 
thread library for i386, amd64, and ia64.  For alpha
and sparc64 the library is not changed and remains libkse,
and links are installed so that libpthread -> libc_r.

The gcc -pthread option will be changed in a separate
commit so that it links to -lpthread instead of -lc_r.

976bb368f6 For the amd64 we need to do some extra stack alignment fixups. Otherwise 
we can end up with some threads with a non-16-byte-aligned stack.  This
causes some interesting side effects, including general protection
faults leading to a SIGBUS when doing floating point or varargs.  This
should be just a verbose NOP for the other platforms.

Otherwise, libthr would fail this test because it doesn't allow
