siege and libpthread

There are problems (segfault) running siege (web benchmark program) on a 
recent FreeBSD 5.2-current (a few days ago). When I switch it to libc_r 
via libmap.conf, everything works ok. Since the software is ported to a 
large number of platforms and works ok, it's probably a libpthread bug :)

Siege uses threading to make simultaneous HTTP requests. I tried with a 
recent release (2.59) and beta (2.60) version if siege, with same behaviour.

This does not happend with small number of threads (2-3), but if I 
specify a larger number (usually 8+), it crashes in the middle of work.
