Remote cross-platform MFC has risk of gem crash

Running a markForCollection (MFC) from a remote gem that is on a machine
with a different byte order than the stone, and therefore requires swizzle,
can result in a gem crash with a preceeding message in the log:

"ObjSupSwizzlePageGet error on page 16778280 oop 10944580 (message can
be ignored if no further problems)"

Byte swizzling is required when a remote gem is Windows or Linux, and the
stone on Solaris, AIX or HP (or vice versa).

Workaround

Avoid running MFC from gems that are remote from the stone and on a machine
with a different byte ordering.
