Here is a WAG for you.

In my SVR3.2.1 there is a shell program that gets run around any
XENIX executables.  It does some cleanup on the arg types where
there were compatibility problems.

The same thing seems like a likely possibility for any SVR4 that
whants to run SVR3 stuff but that has some problem with something
spesific.

That would make it take more memory.

Rob.

Like I said, just a WAG. (I smell a disclaimer ;-)
