Relative speed of Bourne ... (not really)

[Doug Gwyn <gwyn>]

The other main thing in moving the SVR2 Bourne shell to 4.2BSD
is to do something about signal() and ustat().

On some architectures (IBM, Gould), the memory allocator has
to have a small change made since it makes assumptions about
run-time storage layout.

P.S.  Watch out for the new "echo" built-in; it processes
\ escapes and does not know about the -n option.
