[comp.lang.smalltalk] Any Spare Bits in Object Header?

objtch@extro.ucc.su.OZ.AU (Peter Goodall) (05/14/91)

Hello,

I want a bit to mark inthe object header of any, prefereably all, releases 
of the Digitalk Smalltalk/V products. 

This is to let me unload recursive objects linearly to a file, without
having to use dictionaries, and other slower structures.

I would even consider suspending garbage collection for an interval. As
long as the bit isn't used by the GC.

Any ideas?

Thanks
