NACK on this one.
The Monitor object should be restricted to HMP. This patch spreads it to
what's going to be the QMP implementation of screendump.
The first step here should be to convert the screendump command to the qapi,
and lock the HMP shell in hmp_screendump().
However, this brings a new interesting problem: the HMP implementation is
actually a QMP client, meaning that it won't have a way to figure out
screendump completion either :)
Some solutions that come to my mind:
1. Pool the screendump file creation from a timer.
Cons: it may return before the file is fully written to disk
2. Use inotify
Cons: what about windows?
3. Introduce query-screendump that returns the last screendump status
Cons: this is actually making screendump async
Anthony, do you have any ideas?
Btw, I've started doing the screendump conversion to the qapi, I'll post it
soon.
