I've been struggling with this for a few months, on my WinXP SP3 (32-bit, dual-core) host. I avoid compiling on it, because after a few minutes CPU goes to 100% even after I exit all Cygwin processes, and once that happens the only solution is to reboot... which I usually do with the reset button, because by that point everything is so slow that even rebooting takes 15 minutes. There's no PCA or Superfetch service on my host. I'll try shutting down other services to see if that helps.
