Given it's on Windows, any suggestion for how I would get hold of this?
(Process Monitor tool perhaps?)

Hmph.  When a new command is received, there's some amount of parsing
overhead that happens before it changes the status display to not-IDLE,
but it shouldn't be minutes' worth.  Can you get a stack trace next time
that happens?
