cannot shutdown defunct clients |

Indeed the ODB command "cleanup" really works. I have used it several
times with the TWIST DAQ and regularly with the BNMR/MUSR setups where
we have these stubborn clients (ie feepics) that do not want to shutdown
cleanly.
But there is one problem with "cleanup". It has a hardwired timeout of
2 seconds. This is a problem for tasks like lazylogger which set a timeout
of 60 seconds when moving the tape. So BEWARE, if you issue the "cleanup"
command, it might kill some clients who have setup their timeout to longer
than 2 seconds.
I have asked Stefan to change this before. He said that, to be effective,
the timeout value used for "cleanup" has to be rather short.
One possibility, would be to allow for a user entered "cleanup" timeout.
The default could stay at 2 seconds.
