> suddenly, an ODB semaphore timeout...

I am wondering if something bizarre is going on, like the system clock going backwards. I heard of things like that 
happening in virtual environments.

https://stackoverflow.com/questions/4801122/how-to-stop-time-from-running-backwards-on-linux

I added some debugging information to the semaphore locking code. Please update to commit 
eb625af119067f6d702211542d88a28ccb57ad2c of src/system.cxx (plus small change in include/msystem.h) and try again.

Now for each timeout it will print detailed syscall and timing information, if time goes backwards, it should catch it.

K.O.
