I have an idea about this, but this is not a one-liner and might not
work either. The hard part is wait_event() in request_wait_answer().
Probably also needs libfuse support, because libraries might complain
when they eventually reply, but the request is not there anymore. We can
work on this during my x-mas holidays (feel free to ping from next week
on), but please avoid posting about this in unrelated threads.

Thanks,
