Oops, you're right of course. Seems like a documentation bug in 1.x.

Yes, but there's a catch at least with the 1.x versions: the timeout
variable in the target's PROBE_CONF section appears to have a totally
different meaning than the timeout variable in the '*** Probes ***'
section.

If you specify 'timeout=x' in a target's PROBE_CONF section, it will be
passed as the '-m' argument (maximum seconds) to the curl command line. 
OTOH, the probe-specific timeout property means how soon an unresponsive
curl process should be killed.

There are probably going to be incompatibilities here when upgrading to 2.x.
I'll have to check on that.

(This is all from reading the code, I haven't tried any of these lately.
Hope this helps anyway.)
