Well its already in.  (FYI its also PGC_SIGHUP)  I included it here
because I wanted to make sure it made sense in context of the other
new plperl GUCs.

I *think* its there so people can:
-"use" the same modules in both
-profile both plperl and plperlu code easily (which is really the same point...)

The main difference between on_init and the other two is the later get
eval()ed in while the former is treated as "perl -e". (Did I get that
right Tim? I did not really look over the first patch).  Im not sure
if there are different consequences for that style...  But I would
venture its done that way so we can profile any perl interpreter
startup stuff we do in plperl.c or the src/pl/plperl/*.pl files.

So there might be a reason for it...
