WHOO! RE: exceptions and threads---a survival tactic!


I stayed home for a while this morning instead of going to work in
order to install the March 8th snapshot with thread-safe exception
handling. (My platform is a dual-pentium Linux system, and I'm using
LinuxThreads.)

Two words: it works!

Six word caveat: as far as I can tell. 

I performed a number of tests with a program that would consistenly
core dump without the thread-safe eh, due to concurrent exceptions
triggered by related events. About 10-20% of the trial runs, the program
would not crash, due to a different order of execution of the threads.
I was able to successfully run it about half dozen times without
problem.

I did correctly enable the thread-support; there are unresolved symbols
in libgcc.a to various POSIX threading API functions such as
pthread_setspecific.

:)

Hooray! Good work, people!

What I will try next is compiling a C program and see if it the
linker complains about undefined pthread-related symbols.
