Try the attached changes:

"Change Set:		LessFullGCs-ar
Date:			12 December 2001
Author:			Andreas Raab

Remove the need for garbage collections in two cases.

Case #1: File operations required (possibly full) garbage collections on
certain operations. These are unneeded if the file registry does not contain
a file with the same name. In this case, the failure to perform the
operation cannot be due to a dangling file handle and thus we don't need a
GC.

Case #2: Socket creation required a full GC if the creation failed. This can
only happen if the number of open sockets is above a critical threshold (and
therefore exceed OS resources) and some sockets are dangling (and could be
used to free up resources). A registry threshold can prevent execution of a
full GC until we have at least a certain number of sockets open.
"

Cheers,
