I noticed that MacVim was showing up in the top 5 processes on the CPU
section of iStat Menus, with anywhere from 1.7 to 5% CPU utilization. This
is while MacVim was idle and another application was in the foreground.
Here's a typical sample taken with the Activity Monitor. It all looks like
Mac framework stuff to me.
