FWIW, I had a similar issue with r11324, ie. TSVNCache was consuming 100%
CPU. I attached the process to a debugger and found that two threads were
busy-looping on a failing CreateNamedPipe() call (in functions PipeThread()
and CommandWaitThread()). There was no file system activity at all. I
"fixed" this by placing a Sleep(200) call when the pipe creation failed.
However, the problem disappeared with a new build and reboot, so I forgot
about it.
