[1.7.9] frequent five-second pauses for no apparent reason

As of today, I'm experiencing intermittent five-second pauses when I
run Cygwin processes. Even the simplest executables (ls, mkdir) can
experience these freezes. I can't break out of them with ctrl-c. I
stripped down my PATH to /usr/bin with no effect. My Cygwin
installation and home directory are on a local drive.

It sometimes seems to happen on process exit. For example, 'ls --help'
will sometimes print the help and then freeze. Long-running
interactive processes (vim, less) don't seem to freeze during

I can make it happen more often by stressing the CPU with other Cygwin
processes. For example, a terminal running "while true; do time
ls>/dev/null; sleep 1; done" will only show the problem once in a
while. If I open another terminal and run "while true; do true; done",
it happens constantly.

This only started today, when I ran setup.exe and upgraded everything,
including the cygwin package. Was something changed that might be
causing this?
