I've used a similar data structure for a special-purpose allocator
before, and it had extremely low allocation time overhead---
basically a few memory references for every level of the tree
in the common case.  Unless for some strange reason it pessimizes
processes with a small number of file descriptors significantly,
it would be really great to have this in the tree!
