This seems wrong. You are passing uninitialized pointers to g_cond_init. It seems like you'll need to allocate a GCond structure first. Please use the WTF allocator too. :) The same pattern should be used for the GMutex stuff.

Would it be easier to simply use WTF threading primitives here?

And here you would need to free the allocated data.

Use WTF allocator and free allocated memory after clearing the mutex
and gcond.
