I'll do it as a bug fix, but I do need Jens to make sure nothing else
breaks first.  Best I can tell, the state model for compound commands
like flush doesn't expect us to change the request type ... nothing puts
it back to REQ_TYPE_FS.  In your case, the flush is the last command
sent, so there's no problem ... I just worry we will get an obscure
problem later on from something that does a BLOCK_PC prepared first
command.
