I would argue "the problem with make"... ;-)  I think it's pretty
clear that

a b c: foo
     buildabc

does not require that 'buildabc' be run three times.  Make
should be able to note that 'buildabc' was already spawned
for 'a' and just add 'b' and 'c' to the wait list for
that operation, rather than running additional copies.
