Again, I said I'll send a patch for the syminitialize issue being called
twice (but I need to figure out the semantics for the SymCleanup, which
seem to be ackward...), but that's unlikely the cause of the later
crash, so you don't need to spend too much time on the dbghelp issue (if
you really want to be sure, in SymInitialize return TRUE if we've found
an existing process with the same handle)
