There is (an can be) nothing rsync-specific about the
tempfile names so it would be prone to mistake another file
named the way rsync tempfiles are for an rsync tempfile.
That is why the names are semi-random. Even if we came up
with a way to differentiate the rsync tempfile from another
file the semi-random tempfile names would require that such
a check to scan each file's parent directory for each file
synced and that would be a lot of added overhead.
I can't see doing that.

Sounds like a process issue. You might want to either take
rsync away from the impatient or wrap it in something that
maintains and tests a single transfer lock file and can
either refuse or wait until the running transfer is
complete.
