I have done these on UnixWare so far and now plan to do some similar
things on FreeBSD (no SMP yet) and pthreads. Are there any special
installation or other notes for using pthreads on FreeBSD? To
what extent is lib++/g++ thread-safe?
libg++: I haven't looked, but I would guess "not very". Look for
anything with static data (.data or .bss); if it's not something that
can be made "const", it's probably not safe. Don't manipulate any
libg++ object from multiple threads at the same time, unless you
verify yourself that none of the operations can alter the contents;
there are no locks.
g++: Don't use set_new_handler from multiple threads. Forget
exception handling and profiling.
