[cross-project-issues-dev] Builds consuming all CPU

[Thomas Hallgren <thomas@xxxxxxx>]

Over the last couple of weeks, I've done a 'top' from time to time when 
I feel that my builds take longer then they should. Very often, I see 
this at the top:

 12252 egwin     20   0  668m 168m  11m S  115  1.1   0:09.27 java

A hint to egwin and others that run very heavy builds. The message of 
the day on the build machine states:

"If you run continuous builds, you should start your shell processes 
with nice -n 10 (command) to be kind to others."

Another entry that isn't that uncommon at the top is:

 29702 hudsonbu  17   0  584m 101m 7372 R  124  0.7   0:25.09 java

which of course raises the question, why isn't Hudson running its jobs 
with nice -10?

The jarsigner seems to be one of the few that actually does this, and my 
builds always waits _very_ long times for it to complete.
