For example, for a command of the form bin/tahoe put --mutable localfile URI:DIR2:.../filename (putting a new version of an existing mutable file in a mutable directory), we seem to be doing three readvs on the directory, and two readvs and a writev on the mutable file. This seems more than necessary.

(Test done on the cloud backend; not sure yet whether it also happens for trunk.)
