I was wondering if it was possible to use "combination filter" as part of a configuration matrix to run the job ONLY on slaves that are currently on-line. If the code provide runs inside the Jenkins virutal machine (does it?), then perhaps we can return true only if the slave under consideration is on-line.

If that is possible it would be a great addition to the docs page for matrix jobs. If not, it would be nice to have that ability from this feature.

USE: I want to check the disk space on all slaves. I create a maxtix job and tell it to run on all slave. However, if a single slave is down, the job waits forever for the slave that will never be there . . . instead of ignoring the off-line slave and running again at the next cron time.
