It looks most definitely like a bug. /.suspended is used as a lock to
prevent multiple instances of the script from running. When /.suspended
exists, it contains the process ID of the script doing the suspension.
If a second script is started, it sees the file (after the patch) and
checks whether the process with the process ID is still alive. If it
is, the second script exits.
