PHP does a pretty good job from protecting against this. Installing 
mod_php4 from ports will also turn on the --enable-memory-limit switch, 
which causes PHP to terminate if more than x MB RAM are taken (this 
shouldn't segfault Apache). The "classic loop from hell" should also be 
undoable, since PHP has a 60 second execution time limit. You might want 
to run your httpd process in gdb to see what's going on when stuff 
segfaults. If this is indeed a problem with PHP, I'm sure the developers 
would like to hear about it ASAP!
