Okay, joerg and me could speed pkgsrc building up a bit by telling pkgsrc to use the builtin for test and [.

However, look at this:

avg fork parent: 0.000148
avg fork child: 0.004091

(rough rough numbers, will be off if there are multiple processes running concurrently)

5ms seems to be a good estimate for fork performance.  but mind you, that's the child which is taking longer.  This means the parent returns *first*, then starts wait4'ing (usually, or blocks on a read or so), then some time passes and then *later* the child returns from fork.  Seems wrong to me.

so much statistics for now, cheers
