That works fine for emp.sty, where I have only a few graphs. The problem
ist feynmp.sty, where I currently have ~80 graphs within something like
30 or 40 displayed equations (still increasing). At least at the moment
I find it more practical to have one 'fmffile' per file in a multi-file
document and make occasional preview-latex runs on the whole buffer.

Thanks, that helps. Really nice would be a possibility to switch between
enabeling '-shell-escape' or not, since I don't want MetaPost to process
the files, even if nothing has changed.

Interesting indeed. It seems to come from emp.el. If I understand the
code correctly, then this variable only controls whether this
'\immediate\write18{mpost ...}' statement is inserted. So probably not a
security hole, but still strange.
