Why not move the loop into some Makefile and let make take care of the 
parallel execution? Something among the lines of

results := check1.out check2.out ... (generated)
coccicheck: $(results)
	cat $^

%.out: FORCE
	... run given test and store its result ...

then the user can simply type make -j6 coccicheck.

Note: I haven't seen the patch, I only got Nicolas' mail now.
