Subject: [PATCH] tests: limit per-suite forks to cpu count

this is mostly fine to thrash the cpus on beefy desktop computers, but
it completely destroys travis's wimpy 2cpu/2gb ram configurations and causes
all the tests to fail

instead, restrict forking to the number of cpus detected and wait until a fork
exits before beginning a new one
