Subject: OpenMP progress report bug with multiple 1 thread instances


I'm running two instances of OpenMP john 1.7.9 (non jumbo) for DES cracking from two different directories, cracking with different rulesets... I'm using 

export OMP_NUM_THREADS=1 

...for both shells, as I have a dual core cpu and each one is assigned to one instance (priority -10 for the first and 19 for the second).

Now... 

This is the second instance that I started running a few hours ago

...and this is the first instance which is running for two days

...so it seems that, at the exact point of time when the second instance started (a few hours ago), the first instance got a reset in its progress report to 0%  - but continued cracking ok. The 2 instances are running from separate directories so no interaction between them.It seems like a trivial / minor bug, but thought to report it anyway.
