translated from Scheme+ to Scheme:
(define unified-minterms-set-1 (map function-unify-minterms-list
minterms-set)) ;;(par-map function-unify-minterms-list minterms-set))

The definition of 'function-unify-minterms-list' and 'minterms-set' is missing. Without a test case, we can only speculate what's going on. (E.g., maybe it grabs a mutex).
