Paul,

The -n switch keeps cron in the foreground. This is advisable when 
cron runs under cygrunsrv.

Some of your problems are due to launching a new cron daemon while an 
old one is still running.
If you experiment with cron, you can view the cron log by using "cronevents"

2010/03/01 01:38:45 [Paul] /usr/sbin/cron: PID 368: (CRON) STARTUP (V5.0)
2010/03/01 01:47:26 [Paul] /usr/sbin/cron: PID 2508: (CRON) DEATH 
(can't lock /var/run/cron.pid, otherpid may be 368: Resource 
temporarily unavailable)

I will think about your SIGHUP request when I have more time.
How do other Cygwin services handle this?

Pierre
