But it was recently made thread local. If the value left
in it at the end of one request was smart allocated, the
next request would try to free it - but after its already
been swept.
We could make this RequestLocal, but that seems to add even
more overhead. We could probably make it a __thread TypedValue,
and just set it to uninit at the start of each request (and then
tvAsVariant() where its used). This just puts it back to how
it was, since global_variables() is already being dealt with
appropriately.
