cygwin randomly pauses under Win2k

Tue Apr 16 09:18:00 GMT 2002

I have this wierd behaviour, and it is causing some stats that I 
run to whack out.....
Every now and again (every 15-30 minutes or so), my cygwin apps
pause for 1-2 MINUTES.... I have written a simple script to capture
this behaviour:
$ cat doit
#!/usr/bin/bash
while [ 1 ]
do
 echo `date` Starting >> doit.log
 /usr/bin/time -o doit.log -a sleep 60
 echo `date` Ending >> doit.log
done
I have also written a quick sed script to filter the output from time:
$ cat gettimes
#!/usr/bin/sed -f
s/^.* \([^ ]*\)elapsed .*$/1円 elapsed/
/^0inputs.*$/d
And here is some of the offending output
Tue Apr 16 09:40:53 2002 Starting
1:00.13 elapsed
Tue Apr 16 09:41:54 2002 Ending
Tue Apr 16 09:41:54 2002 Starting
1:00.11 elapsed
Tue Apr 16 09:42:55 2002 Ending
Tue Apr 16 09:42:55 2002 Starting
1:00.21 elapsed
Tue Apr 16 09:45:45 2002 Ending
Tue Apr 16 09:45:46 2002 Starting
1:00.16 elapsed
Tue Apr 16 09:46:46 2002 Ending
Tue Apr 16 09:46:47 2002 Starting
1:00.16 elapsed
Tue Apr 16 09:47:47 2002 Ending
What's interesting is that between seconds 42 & 45, 
time shows an elapsed time of 1:00.21, but the system clock has
actually elapsed 2 minutes & 50 seconds, (unless there is some
major hangups in the invoking of the echo and/or `date` commands).
I am working on this machine, so I know that there are no 2-3 minute
pauses in user responsiveness....
Has anyone else experienced this kind of behaviour??
Thanks.
