However, look at this:

avg fork parent: 0.000148
avg fork child: 0.004091

running concurrently)
Okay, less rough numbers:

122991  104/s   fork

avg fork parent: 0.000157
avg fork child: 0.002563
so if we assume that the parent always waits for the child, it'll take 0.267 seconds per second (in average) to fork?  That means 1/4 of the time is just spent until the child start running.

the above numbers include vfork, these are without:

avg fork parent: 0.000144
avg fork child: 0.002556
same, basically.  Maybe teaching sh(1) to use vfork could give some performance improvement?
