pending patches

[Ken Raeburn]

Hi.  I've sent in some patches recently that haven't gotten checked  
in, and haven't gotten much feedback (except, one of them is unneeded  
if BDW-GC is folded in, which we all want but isn't a given).  Could  
someone please take a look and maybe incorporate them, or let me know  
what I should do to improve them?
