Hm, could that early initialization be deferred until the first
pmNewContext type call?  Before that point, there's no way to do use
the info anyway.  (Maybe something like the event.* metric cleanup you
did a few weeks back?)  Or in the early-init non-context case, drop or
print the error message and not store it?
