Subject: SIGALRM and new 'done' method

Hi, just in case anyone has an answer.

While as was trying my 'done' tree, i noticed that when i run './john 
-t', at some point, (no matter which [sequence of] formats) john exits 
with an "Alarm clock" message. Seems SIGALRM is not handled as expected 
in this multi-formats session.

The message can be seen below. It happens on AMD CPU and GPU and bull's 

Anyone has an idea or suggestion?

Commenting 'opencl_process_event()' helps.
