Bug Description

CP candidate.

From Tim:

LibraryFileAlias:StreamOrRedirectLibraryFileAliasView time outs as shown by
this oops:
   https://lp-oops.canonical.com/oops.py/?oopsid=1607EA56

Happened about 490 times in the last week.

This causes time-outs on the branch merge proposal page as we get the diff from
the librarian.

To note the obvious: this is not about SQL. It's probably about network time somewhere.

One example: OOPS-1607EA56
SQL time: 475 ms
Non-sql time: 189078 ms
Size of file: 8K

Another example: OOPS-1619EA1534
SQL time: 118 ms
Non-sql time: 189066 ms
(I don't have access to this file to determine the size)
