I've built the pkgsrc 2007Q1 thunderbird but I can't reproduce a crash on 
startup. If its dot dirs are available, thunderbird seems to work with 
libc_r, vanilla libthread_xu and libthread_xu + prio patch. However, if you 
remove the dot dirs and start thunderbird with the symlink pointing to 
libthread_xu, it gets stuck waiting for two locks (presumably two threads do 
the waiting, ktrace is not lwp aware so doesn't help much). Kill it, and next 
time it starts up just fine. Given that this doesn't happen using libc_r, 
chances are the locking code in libthread_xu could use some debugging. This 
would be fun to do (especially if it turns out the bug is in the mozilla 
code :P), but I can't volunteer.

That said, I think the two patches I posted can safely go in. Please commit 
while they still apply :)

Thanks,
Aggelos
