thunderbird-3.0.6 stuck in ucond upon start

[Etienne Robillard]

Could this be a side effect from DEADLKRES or as a result of
a exclusive mutex lock (lock order reversal) ? I'd add option 
DEBUG_LOCKS and/or
WITNESS_SKIPSPIN, to disable witness checks on spin mutexes, as
explained in the NOTES file.

cheers,
Etienne
