layer. This fixes an ordering problem that would cause the ISR for
the device to run with now power applied to the device. Most cards
failed to deal with this gracefully, and thus would hang on card
eject.
The power down event, for those keeping score, is what causes the
interrupt for the card.
Many folks in the Japanese nomads list have reported this, so I'll be
MFCing quickly for their benefit.

%fs and %gs registers instead of setting them to known sane values.
%fs is going to be used for thread/KSE specific data by the new
threads library; we'll want it to be valid inside of signal handlers.
According to bde, Linux preserves the state of %fs and %gs when setting
up signal handlers, so there is precedent for doing this.
The same changes should be made in the Linux emulator, but when made,
they seem to break (at least one version of) the IBM JDK for Linux
(reported by drew).

particularly help programs which load many shared libraries with
a lot of relocations. Large C++ programs such as are found in KDE
are a prime example.
While relocating a shared object, maintain a vector of symbols
which have already been looked up, directly indexed by symbol
number. Typically, symbols which are referenced by a relocation
entry are referenced by many of them. This is the same optimization
I made to the a.out dynamic linker in 1995 (rtld.c revision 1.30).
Also, compare the first character of a sought-after symbol with its
symbol table entry before calling strcmp().
On a PII/400 these changes reduce the start-up time of a typical
KDE program from 833 msec (elapsed) to 370 msec.

placed in any scheduling queue(s). The process of dispatching
signals to a thread can change its state which will attempt to add
or remove the thread from any scheduling queue to which it belongs.
This can break some assertions if the thread isn't in the queue(s)
implied by its state.
When adding dispatching a pending signal to a thread, be sure to
remove the signal from the threads set of pending signals.

the need to also create the entire ports tree during a `make release'.
The main motivation behind this is that handling the ports tree still
takes a huge amount of time due to the large number of directories
involved, even on modern disks.
The solution is to establish a list of dependent ports that are
minimally required. This list needs to be manually maintained in case
the doc ports toolchain changes, and has thus been broken out into a
separate file Makefile.inc.docports. (release/Makefile has gotten
overly lengthy already anyway.)
