  If you can start eliminating background processes and services from the
machine in question, and run it in increasingly stripped down configuration
until the problem goes away, you might be able to deduce by elimination
exactly what is interacting with the cygwin process and causing the problem.
If you have a debugger such as WinDbg installed, you might be able to make a
good guess at the potential culprits by figuring out which if any apps or
services have installed windows hook functions by running some minimal app
such as notepad, attaching windbg to it, and looking at the loaded modules
list to see if any come from foreign apps or utilities.
