[Numpy-discussion] FIFO/circular buffer class in Numeric?

Has anyone implemented a fast, generic circular array buffer in
Numpy? I didn't see one in the usual searches, but I don't want to
re-invent one either. I did see a number of C implementations like
which could be weave'd, I suppose.
I have some previous implementations I've used, but what I had in
mind was making a new FIFO class with attributes of address,
state<None,reading,writing>, pointer, size etc., and methods like
flush (if I implement it as a memmap) and other things, like queue has.
The important part of the idea is that multiple threads and processes
could fully access it. Currently, I will have an ADC process fill it,
and other processes use it.
I'll post code as I go, in any case.
