Well, I don't run my Folding at Home as a different user (actually, I ran
it as root, though I suppose I should change that now), and I have
noticed the issue still applies even to other non distributed-computing
cpu loads:

"I tried to reproduce this using a simple busy loop in bash, and with
'yes', and by using cat /dev/zero or cat /dev/urandom > /dev/null, each
niced to +19 and SCHED_IDLEPRIO, but for some reason, these did not
create the same sluggishness that folding at home creates. In addition,
these loads did not show up as 'nice' in my Gnome system monitor panel
applet; Instead, these processes showed up as 'system' load, and they
also sped up my CPU despite cpufreq being set to ignore 'nice' loads."

Therefore, this is not just a boinc issue.
