monitor_resume() and monitor_suspend() both want to
"kick" the I/O thread if it is there, but in
monitor_suspend() lacked the use_io_thread flag condition.
This is required when we later only spawn the thread on
first use.
When sending a multi-patch series (yes, even two patches counts), it's
best to send a 0/2 cover letter, to make it easier for automated CI
tooling to recognize the series.
