--- Comment #41 from Tor Lillqvist  ---
Explanation to the backtraces in Comment #39: 

Thread 1 is attempting to lock the oslMutexImpl at 0x2ad7eb0. It has already
locked the SolarMutex at slot #16, in
DocumentStorageModifyListener::modified().

Thread 6 is attempting to lock the SolarMutex. It has already locked the same
mutex that thread 1 is attempting to lock when creating the AutoRecovery object
being used around slot #14.

Thus the suggested patch makes sure we lock the SolarMutex first, in the code
at slot #14.

Here are the backtraces from the two threads that deadlock, as far as I
understand:
