External Command Interface - broken named pipes on Cygwin

Hi,

It seems that Cygwin support for named pipes may have some broken
parts<http://cygwin.com/ml/cygwin/2010-08/msg00459.html>,
causing trouble during porting of External Command Interface.

What I observe that Nagios manages to write to the named pipe for the first
time. Following requests end up with timeouts. I've tried several other
alternatives like blocked or read-only opening of the pipe to no avail.
Things get just worse. My conclusion is that the current External Command
Interface can not be implemented as a stable solution on Cygwin.

Questions:

- Has anybody succeeded porting External Command Interface to Cygwin?

- Do you have any suggestions ? I am considering to move command fifo
structure and processing logic out of Nagios to a network service.
