*G* What did I win?! The next release is named in my honours?! ;-P
(Actually I'd prefer help on that issue much more ;) )

I'd say that the primary issue is in nagios and/or icinga in how it
handles the child process execution and collection of the SIGCHLDs and
wait-ing for the exit statuses. However there might also play a role
stray stderr file descriptor which is left open on the mux process.

You can try to redirect the stderr to /dev/null when you're running the
ssh from the wrapper script.
