  There's something else you could do, if you can spare a few minutes: you could help out by contributing some information that would allow us to diagnose this problem more easily in future.

  These sorts of problems (cpu usage pegged at 100%, or mysterious hangs or fork failures) are often caused by buggy versions of antivirus, antispyware, personal firewall, or other similar security or system-related software that hooks into every running process and - because it doesn't hook in completely transparently - affects the behaviour of the operating system calls that cygwin relies on to work.

  I'm adding code to cygcheck to detect whether any of the software that has been known at some time to cause these kinds of problems are installed on the target system being cygchecked.  The way it detects whether the software is there or not is by looking for keys in the registry, files and directories on disk, or running processes or loaded DLLs in memory, that would indicate that one of the problematic applications is installed.  But I can't do it all myself, because I don't have any access to most of the software that has been reported to cause problems in the past.

  What I'd like is if you could take the attached file, run:

  g++ -o sysinf -DAUTOMATIC -lntdll

at the command-line, then execute:

  ./sysinf.exe > sysinf.txt

and email me the sysinf.txt output file (offlist).

  What that does is to show me a list of all running processes, and another of all loaded dlls, drivers, and any other kinds of executable modules, which I'll use to add as many methods of detection for as many of the troublesome applications as possible.

  If you have even a few more minutes to spare than that, if you could take a look in your registry, you'll probably find some interesting keys under HKEY_LOCAL_MACHINE\SOFTWARE, indeed most likely under HKEY_LOCAL_MACHINE\SOFTWARE\McAfee.  It would be very kind if you could list a bunch of them for me, either by exporting that key from the registry to a file and sending it to me, or just by making a few handy notes of the most interesting-looking keys under there, such as for example shown in this email sent yesterday to the cygwin-talk list:

Can't think of a witty .sigline today....
