Looks like a deadlock during crash handling, via the allocator. CrashReporter::PairedDumpCallback is allocating a string. Not sure who's holding the allocator lock.

We're taking a snapshot of the main process and that pauses all threads except for the writer... we might be hitting any other thread holding that lock. This is yet another problem that would be solved by fully OOP minidump generation.
