I just executed some additional tests on the 2x IA32 box:

(*) Suse 9 base (kernel 2.4.x, libpthreads = linuxthreads I think)
 -> "./test 1 1" doesn't even start; have to kill with ctrl-c (won't
timeout)

(*) Suse 9 (linuxthreads) + kernel 2.6.8.1
 -> "./test 1 1" doesn't even start (same as previous)

(*) Suse 9 + kernel 2.6.8.1 + recent glibc (with NPTL)
 -> Same results as with FC2 (i.e. timeout)



So it looks like the distrib is not influent, only kernel + libc is
important (I thought at first that only the kernel was influent).

I could not test NPTL with another kernel as I compiled this one with
--kernel=2.6.8.1 and I don't know if any other results would be
trustable.

I did not know about the SuSe 9.1, I'll have a look tomorrow.

Cheers,
Seb. :)
