 FWIW, I ran the test at http://berlin.ccc.de/~packet/fork_test.c, 
 modifying it to malloc() 10 MB first, to make it have about the same size 
 as a csh process.  On my 1.8 GHz amd64 running 7.0-RELEASE I get
 
 measured fork time: 251396 nsecs
 measured vfork time: 243734 nsecs
 
 a difference of about 3%.  So the penalty for switching back to fork() 
 instead of vfork() wouldn't be very much, and this is certainly the 
 simplest fix -- a one-byte patch :)
 
 Thoughts?
