Passing an argument to this function, which is way way way down in the
call stack, isn't practical.  And it would be irrelevant to most of the
url.el code, anyway.

Being able to discern whether you're running code asynchronously seems
like a generally useful thing.  Our goal is to make Emacs more
asynchronous, so we need a way for functions to know what context they
are being run in, so they know what they're allowed to do.
