I was learning from @jdelong and he said that you should use
double quotes for local includes and angle brackets for library
includes. I asked why our code was the way it was, and he said he wanted
to clean it up. I beat him to it :)
Conflicts:
hphp/runtime/base/server/admin_request_handler.cpp
hphp/runtime/vm/named_entity.h
Before we've jitted the first bit of the TC, having so many
threads leads to a pathological situation: we accept a bunch of
requests (135) and have all of them running in the interpeter,
starving the JIT thread that is trying to make them all go faster.
(Perf record of a machine in this situation shows the vast majority of
the time in dispatchImpl, SrcDB::find, and enterTC). This diff tries
to solve this by limiting the number of threads to the number of cores
for the first N requests.
This change is mostly for FB internal organizational reasons.
Building is not effected beyond the fact that the target now
lands in hphp/hhvm/hhvm rather than src/hhvm/hhvm.
