The previous version ended up being (at least sometimes) wrong after
the recent deployment system changes.

This requires manual steps on deploy to each of staging and prod:
(1) Run the new update-deployment code to setup the initial deployment directory.
(2) Restart all the programs running in screen sessions.
(3) Deploy the nginx changes and restart nginx.

restart-server has been relatively slow recently, and it'd be nice to
know what it is spending its time doing when it hangs for a few
seconds.

Our previous code could in theory end up clearing the caches it had
just filled, if Tornado's cache filling work happened to be faster
than the memcached flush.

At Ksplice we used /usr/bin/python because we shipped dependencies as Debian /
Red Hat packages, which would be installed against the system Python. We were
also very careful to use only Python 2.3 features so that even old system
Python would still work.
None of that is true at Humbug. We expect users to install dependencies
themselves, so it's more likely that the Python in $PATH is correct. On OS X
in particular, it's common to have five broken Python installs and there's no
expectation that /usr/bin/python is the right one.
The files which aren't marked executable are not interesting to run as scripts,
so we just remove the line there. (In general it's common to have libraries
that can also be executed, to run test cases or whatever, but that's not the
case here.)

Manual deployment steps: The same Nginx reload as for "Get rid of the
static-access-control mechanism". If deploying both commits at once,
just do it once.
