	You can't do dynamic page allocation rith the rm*() functions. These
functions simple impose a first fit allocation algorithm over a block of 
existing memory. They are useful, but not in your case because you want to
allocate fixed size buffers, so you're better off using a freelist allocation
scheme. If you like, email me and I'll send you some sample code.

	I'm hoping that If I keep this conversation going, somebody might 
jump in...
