Hmmm, sorry, that's a thinko.  When doing an infcall, of course you
don't go through fetch_inferior_event...  So a cleanup would indeed
fix most cases, although a few times, like when remote.c pops the
target due to losing the connection, a cleanup wil still set the
async mask in the wrong target.  (The parameter to target_wait
would solve this 100%).

Don't you love having two ways to do the same thing?
