I don't know it this was unique to my machine, but am
reporting it in case anyone else runs into the same

the patch for Security Update for DirectX 9 for Windows
2000 (KB904706) hung during installation, with an
instance of cygrunsrv hogging 100% CPU, until I had
stopped every last one of my cygrunsrv processes. I
don't know what the Microsoft update was trying to do
to running services during the update, but it obviously
didn't interact very well with cygrunsrv.
I've just installed this update too. cygrunsrv was using about 80 %
of the CPU while CSRSS.EXE was using what was left. Here are backtraces
from cygrunsrv and cygserver at the time the hang occured - both look
pretty strange, both indicate that the programs are stuck in NTDLL.DLL.
