Thanks for mentioning these two items. I installed the attached two patches into 
master. The first arranges for SUSPICIOUS_OBJECT_CHECKING to not be defined 
unless one compiles with ENABLE_CHECKING, which should remove the Ffset hack in 
production code; the second removes that 25-year-old GC workaround that hasn't 
been needed for quite some time.

Actually, all that SUSPICIOUS_OBJECT_CHECKING code can be removed. But one step 
at a time.
