Subject: SIGPIPE in t9300-fast-import
Message-ID: <0BB1933F-1C3D-4C24-9C91-263121BF55FB@gernhardtsoftware.com>

The new cat-blob test (9300.114) is failing for me on OS X, and has been since it's introduction in "85c6239 fast-import: let importers retrieve blobs":

ok 113 - setup: have pipes?

I don't have the tuits right now to dig into this, but "trash directory.t9300-fast-input" has a good response (`cmp expect.response response` is true), but has no refs/heads/copied.  I can run help provide diagnostics, if anyone needs more data.

PS:  Isn't t9300 getting a little crazily long?  Is there a good way to split it up by feature or something? It runs quickly, but finding were something is failing is getting a little difficult.
