with-timeout-suspend
with-timeout-suspend is a compiled Lisp function in `timer.el
'.
(with-timeout-suspend)
Stop the clock for `with-timeout'. Used by debuggers.
The idea is that the time you spend in the debugger should not
count against these timeouts.
The value is a list that the debugger can pass to `with-timeout-unsuspend'
when it exits, to make these timers start counting again.
