disposing of records trouble?

[Eliot Handelman <eliot@clarity.Princeton.EDU>]

Hi, 


I seem to be having trouble diposing of bitmaps. Is this the right
way: (DISPOSE-RECORD MY-BITMAP :BITMAP)? Is this sufficient, or do
I need to force a GC too? I really don't understand how memory is
being deallocated, but our program slows down to a crawl and then
gets "stuck" inside the GC after a while and the only way to get
out is to shut down the machine. 


Help please, this is a critical issue for a project that many people
are dependent on.


Thanks,
