The solution is to stop the subprocess before inserting the contents of
the selection into another client.

It's not a bug.  It doesn't have to be fixed.  If your particular use
case is okay with running Lisp while waiting for a process to complete,
then it should use accept-process-output, not call-process.

In the meantime, allowing timers and selection converters to run inside
call-process sounds like it will introduce many new bugs...
