Some of our web-servers take a while to restart (because some custom

How hard would it be to implement a separate signal-handler, which
would -- upon receiving, say, SIGUSR2 -- reopen the log-files without
performing a full restart of each worker? That would provide for a
possibility to log straight into a file and rotate that once in a
while
without a full restart of the httpds.
What you're probably after are piped logs:

If you pipe the log to something like cronolog, cronolog is able to
rotate logs for you without needing to restart httpd.
