Isn't this just another moving part? (Moving parts are generally
considered bad news when you're trying to engineer a secure system.)
And has there been any review of git wrt. if it is robust to malicious
servers? (E.g. if I do a "git fetch", can the server I happen to be
talking to just spew data at the client indefinitely to, for example,
fill up its disk or to prevent it from ever progressing?)
