Question about rtld-elf. Anyone?.. Anyone?

[Daniel Eischen]

So I was glancing at rltd-elf, specifically lockdflt.c.  There
seems to be an assumption that sigprocmask() can be used to
protect a thread from being swapped out.  Am I reading this
right?

There are no such guarantees with libpthread.  A thread
will be swapped out whenever its quantum expires, and if
you've got higher priority threads, they will always run
before those of lower priority -- even if they are spinning.

I'm trying to debug weird hangs with mozilla.  Once it
hangs, I can't kill it except with SIGKILL, and then 
it seems to be stuck in symlook_obj().
