To reduce configuration time, we fork some threads to compute the Java
version for the various configured Javas. However, as the number of
JAVA${N}_HOME variable increases, the current implementation creates as
many threads as there are such variables, which could be more than the
number of physical cores on the machine. It is not likely that we would
see benefits to trying to execute all of these once beyond the number of
physical cores (maybe simultaneous multi-threading helps though, who
knows. Therefore, this commit limits the parallelization here to the
number number of physical cores.
