Problem with Cygwin/FC9

I am having a problem where certain applications run very slowly on Cygwin,
but not on the console. These applications work fine on Cygwin from FC6.
This doesn't affect all applications. The slow applications often seem to
lock up the entire Cygwin subsystem, although things get unlocked if the
process that is slow is killed from another terminal. The Windows sysem
continues to function normally.
Interestingly, I can't see excessive CPU use in any of the boxes concerned,
nor much in the way of network activity. The FC6 server is a 700 MHz
Athalon, the FC9 a 2.2G Core 2 duo. A few examples:
Galeon - FC6 21 seconds, FC9 9 MINUTES 38 seconds
Evince - FC6 4 seconds, FC9 3 minutes 12 seconds
emacs - FC6 9 seconds, FC9 10 seconds
gnome-system-monitor FC6 10 seconds, FC9 2 seconds
I can't seem to find a clue why some apps are affected and some not. I ran
FC8 for a short time on the FC9 box and didn't notice a problem, but I
didn't test extensively. The locking up of the Cygwin-X system leads me to
suspect a cygwin rather than FC9 issue, and at this point in FC9's life I
suspect the combination hasn't been used extensively.
