DragonFlyBSD

I've seen that using /usr/lib/libthread_xu.so as default threading
library gdm-binary is hungry of CPU time:

from top output:

PID USERNAME   PRI NICE  SIZE    RES STATE    TIME   WCPU    CPU COMMAND
   750 root       152   0 12380K  4696K STOP    84:16  95.04%  95.04% 
gdm-binary

while with libc_r.so:

811 root       152   0 10688K  3784K poll     0:00  0.00%  0.00% 
gdm-binary
