As far as I know, there's no particular reason that it won't work.

To enable incremental collection, insert a call to
GC_enable_incremental() somewhere at the beginning of the program.

I tired inserting such a call into main() for MzScheme under Linux. It
didn't crash when running MzScheme's test suite, and the sum of GC
pauses was cut in half, while the total run time went up about 15%
(consistent with incremental collection).
