httpd-2.2 and -2.0 specific patch to revert to 2.0.55/2.2.0 handling of the 

stdout channel; do not close stdout in the parent process or reassign it to
\\Device\Null, but keep it open so that the console signal handler continues
to interact with the running "daemonized" httpd process.

Not committed to httpd-2.x; there is disagreement as to whether this is good
behavior for a daemon, and the proper 2.4(3.0) behavior on Win32 may be to
daemonize but properly handle -k stop by the PID file contents.  Many have
asked for this feature who run a minimal httpd.exe, especially from some
removeable media such as CD, and wish to be able to halt it as a console.
