I just thought of a possible workaround for xine: metronom's sync loop might 
be extended to check, if the last known system time and the current system 
time differ by more than a fixed amount (1 second or something). If so, the 
xine process has been suspended (either by ACPI or by SIGSTOP) and we can 
force metronom into a sync jump.
