Or perhaps at the time the change was made fork/vfork was not nearly as
optimized as it is now.  FWIW I was reading the archives about when
/bin/sh became ash, and it was sometime between B18 and B19, so late
1997/early 1998.  That's going on six years ago, and I'm sure there have
been plenty of core optimizations since.
