On linux, the ext2 filesystem is VERY efficient at buffering filesystem
writes (see http://www.tux.org/lkml/#s9-12). If the post data is small
( I don't know what the default size is, but the FILE buffer for the tmpfile
is adjustable with setvbuf) it's never written to disk. AFAIK, the only
problem with this arrangement for small posts is the extra file descriptor
consumed by the apache process.
It might be a good idea to put in a config setting for the FILE buffer size
also- similar to ProxyReceiveBufferSize.
