check_timeouts: avoid unnecessary conversions (#273)

before we were using select, which expected `struct timeval` as
arg. so we needed to do ms -> timeval conversions.

but now since we're using poll, which accepts milisec as arg, there's
no need to do ms -> timeval -> ms. instead have check_timeouts directly
return ms.
