It looks solid to me.  I especially like the supporting multiple
threads bit.

For future consideration, it would be -very- nice if this supported
writing sparse files.  That will, of course, require a BFD change. 
Right now, the dump for a 12-threaded application is about 25MB virtual
size and no more than 1MB physical on-disk size, because the stacks for
each thread are a 2MB sparse region.
