guessing here, but the SYSVSEM and PTHREAD options could cause a disparity
between memory usuage....this is the output from apachectl -V correct? 
you are using the prefork model correct (sorry can't remember).

hmm...according to your results httpd on FreeBSD is only taking 120k
resident, while OSX is using 14megs resident.  the httpd is not taking any
requests either during these samples correct?

hmm...wierd.  never seen the leak restarting apache via rc.d, it shouldn't
as it kills all httpd process the goes through the start function.  so
that may be a bug.
