How about we add code to automatically run gdb and collect a crash dump?
We can't use MiniDumpWriteDump because gdb can't read Windows minidump
files, and windbg can't understand DWARF symbols.

Or actually, how about integrating Google's Breakpad? It doesn't require
a local gdb, and it comes with a minidump-2-core utility that supposedly
lets gdb debug the resulting dump files.
