Did anything got cracked while you were running? There are certain
situations(very rare) in which you might get segfault at the end of
session. For example if something get cracked in the the last chunk of
password there is a possibility of segfault. The problem is that I can't
distinguish when a call to get_key() is meant for status checking and when
 it is meant to get an actual cracked password.

I haven't tested them on two GPUs but monitor freeze could happen when a
large number of hashes are loaded resulting in extremely long kernel run
time. But still, when only one out of two GPUs is used, the monitor
connected to idle GPU shouldn't get frozen.

I will add other modes this week.
