Actually, mpost currently loads the default mapfile once for every
image that contains a string object when prologues:=1, which is a bug
(it wasn't triggered in the plain mem because it does not set

Sorry Oliver, there is no easy workaround for this: the only thing
you can do is create a dummy psfonts.map file with no entries at all
and using an explicit fontmapfile command to load the (equivalent)
pdftex.map, but that is very ugly.

There is now a handful of odd bugs like this, so there will be
a metapost 1.209 relatively soon.

Sure but, as Oliver says, when TeXShow is noticeably slower than the
normal terminal, it does not appear to be using the operating system's
facilities optimally.
