Well, I guess that the standard file discriptor allocation benchmark is
still missing.  It sort of works like this:

1. Allocate n files, (just open /dev/null)
2. Close file[1]
3. Close file[n] or close a file randomly
4. Measure the time that it takes to open two files.

There is an old paper from Mogul in which he identifies file descriptor
allocation as one of the bottleneck of web servers.
