Be forewarned, though, that this can have significant performance impact
because of the byte-stream emulator. Here's a case in point:

When Mike and I were first doing the Java port, we had the class library
in a variable length file and couldn't understand why performance was
so bad. Almost at the same instant, both of us independently discovered
that simply converting the file from variable to byte-stream had orders
of magnitidue better effect on performance.

While that's not an issue with httpd.conf because it is only read
once, there are cases where NOT converting to a byte-stream file
will adversely affect you.
