I am afraid I missed the "base code" where you did the above change.
Are you proposing this change on top of the original w3 code? (That
is, with the original definition of stddebt, etc.?)

Maybe instead of the "100+gcpause" we should add another parameter
for this? Something like "gcpauseminor" and "gcpausemajor"?
