When I run a McCLIM application, according to `top' CPU usage is constantly above 95% or so, and the KDE System Monitor reports about 50% for CPU 1. Here is a typical `top' entry when running the CLIM Listener:
top - 09:52:31 up 3 min, 1 user, load average: 0.37, 0.23, 0.10 Tasks: 78 total, 2 running, 76 sleeping, 0 stopped, 0 zombie Cpu(s): 14.3% us, 36.0% sy, 0.0% ni, 49.7% id, 0.0% wa, 0.0% hi, 0.0% si Mem: 2075012k total, 301272k used, 1773740k free, 11244k buffers Swap: 2004420k total, 0k used, 2004420k free, 165556k cached

When only the CMUCL toplevel is running, it is below 1%. Why is CPU usage so high with McCLIM applications? Is it real or some sort of measuring artifact?
I use the latest McCLIM CVS sources with CMUCL Snapshot 2004-12 under Slackware Linux 10.0. My PC is a 2.8 GHz Pentium IV with 2 GB of RAM.
