path	a pathname string

Word description
Creates a directory in the current-directory that is guaranteed not to exist and return the full pathname. The mechanism for the guarantee of uniqueness is retrying with a unique-length randomly generated filename until make-directory succeeds.

Errors
Throws an error if the directory cannot be created after a unique-retries number of tries. The most likely error is incorrect directory permissions on the current-directory.
