Hmm, this discussion reminds of `SFIO' from Bell Labs (?) (I remember
reading a paper (Usenix proceedings?) on it a long while ago).  

Basically SFIO was a replacement for STDIO, with the proviso of stacking
file input and output primitives.  Parallels to STREAMS or VFS philosophy
could be drawn I guess.  This one could "push" a compression
layer over the regular I/O code and get compressed I/O etc etc.

It also claimed to have better signal handling than the original STDIO code.
