I've managed to track down what was causing this problem (as well as the 
ssh-agent hang, see "1.7.1 ssh-agent hangs with 100% cpu").

It is being caused by the installation of version 2.7 of ESET NOD32 
Anti-Virus software.  I've checked version 4 and it does not cause this 
problem, however if you are still using 2.7 the following work-around 
exists:

1. Open the NOD32 Control Center [sic] and then select "IMON" from the 
"Thread Protection Modules"
2. Click the "Setup" button.
3. Select the "Miscellaneous" tab.
4. Click the "Edit" button in the "Exclusion" group box.
5. Add c:\cygwin\bin\rsync.exe. (Add c:\cygwin\bin\ssh-agent.exe too 
while you're there.)
6. Click "OK" and then "OK" to save the changes and you're done.

E.
