I hope that this requirement is applicable only to the externally
visible efffect.  A few days ago, I looked at assembler output from
GCC 2.8.1, and I think there were some interleaved function calls
(without externally visible effect, of course).

In addition, there are quite a few C compilers which perform massive
optimization in this direction, actually executing function calls *in*
*parallel*.
