Sorry, I dont know how to see syscall number, may be it logged into
/var/log/messages?

I try run via ssh and via su - no difference in speed: 9500-65000 per/sec
depend on instructions set.

I run with -j 1 - IMHO thats why I got no crash.
Now I run with -j 15
./sifter.py --unk --dis --len --sync --tick -- -P1 -j 15 -l 1
and quickly (few seconds - few minutes) get exit code 10:

#0  0x0000000800967db1 in pthread_getspecific () from /lib/libthr.so.3
#1  <signal handler called>
#2  0x000000080121e000 in ?? ()
#3  0x0000000000000000 in ?? ()

Program terminated with signal 6, Aborted.

#7  0x0000000000403a8e in give_result ()

on intel machine same errors.
