checkheads: clarify that we no longer touch the head unknown locally
Since
c6cb21ddf74a, heads unknown locally no longer get any post processing
from obsolescence markers. We clarify this fact by only feeding the list of
locally known new heads to the function. This simplification of the input will
help moving that post-processing earlier in the function.

Profiling of HTTP requests works

A single profile is logged because file logging doesn't append

Install an extension that can sleep and guarantee a profiler has time to run
$ cat >> sleepext.py << EOF

statprof can be used as a standalone module
