I have a different box than before: more cores. Well, I guess that, for my libraries, I can make a preprocessor conditional on SCM_MAJOR_VERSION == 2 to eliminate all smob marking for guile-2.x. Could parallel marking have other, non-SMOB-related, side effects? I can disable it by setting the envirnomnent variable GC_MARKERS to 1. Thanks, Mike
