See my other mail. I meant atomic data access which simply has to be
the case or the os will go berserk :)

The reason to ignore SIGPIPE was to make plugins to bahave like
the main app did before :) They should terminate themselves when Gimp
crashes. So I inotrduced a handler for IO errors on the read channel
which doesn't let them hang around as they used to do before.

But I never claimed the new code to be the correct and final solution.
So if it breaks perl in any way, we will of course have to change it
again.
