Hi Nick, thanks for looking at this.  I was hoping you would.

As I understand it, it already is combined - I know Vladimir started
with a copy of your most recent async patch.  I haven't looked at his
patch yet but it may need to be broken down into some pieces.

Vladimir, what target were you using to test - was it "target async"?
If so, there's already a file handler relevant to inferior events;
"target async" uses the remote protocol to talk to gdbserver, so it
receives events every time there's a byte on the TCP socket.

Shouldn't you be able to use async operations from a command file?
