In-place memory manager, mmap (was: Fastest way to store ints and floats on disk)

[castironpi]

Hi,

I've got an "in-place" memory manager that uses a disk-backed memory-
mapped buffer.  Among its possibilities are: storing variable-length
strings and structures for persistence and interprocess communication
with mmap.

It allocates segments of a generic buffer by length and returns an
offset to the reserved block, which can then be used with struct to
pack values to store.  The data structure is adapted from the GNU PAVL
binary tree.

Allocated blocks can be cast to ctypes.Structure instances using some
monkey patching, which is optional.

Want to open-source it.  Any interest?
