No, I wasn't -- I actually found out about scm_block_gc by googling
"Guile performance."  It came up on a mailing list where some Gnucash
developers were fussing over their build.

Actually, I just tried -- boosting those values actually cuts down on
GC thrashing considerably.  Thanks!  (Plus, I don't actually think
it's out of the question to have the application set those variables
before initializing Guile.)

It does, a great deal!  Thanks so much for the information.
