-# - try to get random bytes from /dev/urandom
-# - failing that, generate output from a combination of quickly-varying
-# sources and gzip. Ignore non-varying gzip header, and extract
-# "random" bits from there.
-# - given those bits, map to file-name bytes using tr, and try to create
-# the desired directory.
-# - make only $MAX_TRIES attempts
