Subject:	long delays on fhandler_base::open with cygwin 1.3.10

I'm using Cygwin 1.3.10 DLL and I occasionally get long delays (>2s !) when
fhandler_base::open is called on a disk file. This occurs sporadically and
is not dependant on the file being opened.
I've included a little strace snippet below. Just look how long
fhandler_base::open takes to return! No other CPU intensive programs are
running and, no, I'm not selecting text in the console window and not
realising it... :-)

Regards
Chris
