QUESTION: launch Jenkins builds/slave connections with 'nice'

[Victor Martinez]

Hi there,

 I've been googling a bit and I couldn't find much information about a way to launch all builds on all Jenkins slaves (well, at least for Linux and Mac slaves) with "nice", only a reference from 2008:

  https://issues.jenkins-ci.org/browse/JENKINS-2742

 That would set the priority of builds to -10, which means that system processes, like cron, zabbix, puppet, etc. take priority. It wouldn't really slow down the builds, but would make the system more responsive when the CPU hits 100%.

 Reason: We have slow SSH login and zabbix monitoring timeouts whenever a slave is at 100% CPU usage.

Thanks so much

Seems like it should be fairly feasible at least for jnlp if you start the JVM with nice. Though I'm not sure at all that kind of thing is inherited. So any step spawned from the agent's running jar might have a nice value back to 0.
