apachectl hardstart?

[Todd Weaver <to...@m2n.com>]

I've had need in the past to stop, sleep, start apache.

The reason for such action(s) has been writing external modules and
loading SSL certificates.

Recently I wrote an SSL self signing generation script, that after
generation required an 'apachectl stop && sleep 5 && apachectl start'
or the like.

Instead of sleeping for an arbitrary time without guarantee of shutdown
before a start request, I added the below 'hardstart'.

hardstart sleeps at most 1 second past the shutdown completing, then starts.

I'm not sure if others would find it beneficial, so before filing a patch,
I figured I'd see if 'hardstart' would be of any use to others.

Or if anybody had any improvements to the code.
(example: throw a different error code for hardstart failure?)

Feedback?

Todd.
