Is there a means of achieving background-only (or nearly so) testing

There is in the mod_jk (SVN trunk).
I've been reading this code now...
The watchdog thread looks very useful. If I understand it correctly,
the watchdog thread can do whatever it feels like but currently mainly
calls wc_maintain, which will only do work at most every worker.maintain
seconds, right?
connection_keepalive does not look like it really my bill, though. I'm
most worried about workers in an error state and ensuring that they are
rechecked every recover_wait_time -- but only by the watchdog thread and
ideally via a ping/pong. Currently recover_workers appears to just put
workers into a recovery state where they'll be elligible to be tried
again on a future request -- without checking whether the worker is
actually accessible. That's fine for some use cases, but explicitly
what I want to avoid.
Are there any thoughts to have an option to have recover_workers() do a
ping prior to returning a working to a non-error state?
And, yes, a watchdog thread in mod_proxy_balancer /and /a reasonable
means of balancer invoking a ping via mod_proxy_ajp would be really
helpful as far as mod_proxy_ajp is concerned.
