just to let you know:

Some minor tweaks in the CPP-Code may have helped but it looks like the
most successful action I could take was switching to the latest code in
the 5.8.x maintenance tree
(http://public.activestate.com/pub/apc/perl-5.8.x/).

Especially the recent thread safety fix for "tr///" seems to have helped
a lot.

I still see senseless error messages like 
-- snip --
(in cleanup) Can't find string terminator '"' anywhere before EOF
at /digibib/tools/lib/perl5/5.8.8/unicore/To/Fold.pl line 108
-- / snip --
although the respective files are perfectly fine, but at least the
processes don´t die anymore.
I can´t see a reason why perl should be unable to read and parse the
entire file but maybe I can fix that by preloading these files/modules
in an interpreter instance which is then cloned for every new instance.
