3.4.0qa8 works fine, but after a while, a NetBSD/amd64 brick stops
responding (while NetBSD/i386 servers seems to work fine, therefore
it looks 64 bits specific). ktrace shows it loops around poll calls. Here
is what I can see if I stop it and inspect with gdb:
#0 0x00007f7ff62759da in ___lwp_park50 () from /lib/libc.so.12

(gdb) list
152 pri = -1;
153 }
154 while (conf->queue_size == 0) {
155 conf->sleep_count++;
156
157 ret = pthread_cond_timedwait (&conf->cond,
158 &conf->mutex,
159 &sleep_till);
160 conf->sleep_count--;
161
(gdb) print conf->cond
$1 = {ptc_magic = 1431633925, ptc_lock = 0 '\000', ptc_waiters = {
ptqh_first = 0x7f7feec00000, ptqh_last = 0x7f7fee000230},

ptm_waiters = 0x0, ptm_recursed = 0, ptm_spare2 = 0x0}
NB: ptc_magic and ptm_magic are correct.
(gdb) print sleep_till
$3 = {tv_sec = 1359902843, tv_nsec = 0}
This is also fine.

Is'nt it supposed to have multiple threads?
