cygwin-1.5.16-1: FIFOs broken


I have a client-server application written in Perl that reads and writes using FIFOs. It works fine under cygwin-1.5.15-1, but fails under cygwin-1.5.16-1 because it cannot read from the FIFO.

To test this, open two shells.  In one shell, type:
cd /tmp
mkfifo FIFO
cat <FIFO

In the other shell, you can send text to the first shell using:
cd /tmp
echo YOUR TEXT HERE >>FIFO

After you're done, just ^C in the first window.

Under 1.5.15, the above works fine.

Under 1.5.16, no text goes through the FIFO. Further, the echo command hangs, and will not terminate with ^C. A 'ps' shows an 'O' for this stuck shell. You have to do a kill -9 on the shell to terminate it.
