I think it's a good idea for reports of server crashes to include their
stack traces, especially if we're going to take no action to preserve
the core dumps.
I asked yonah to extract stack traces, and he did so (below), though
there's some question as to whether shared libraries were dealt with
correctly.
FDel() deletes a file entry from the hash table; the assertion failed
was whether the entry is non-NULL.
I don't have anything else to say :-)
