Note, however, that optimised tail calls are pretty close to the original
idea of co-routines.  In other words, you can jump back and forth between
routines without having to go through the overhead of an ordinary call
sequence.  I have worked long on this problem and GCC (3.4) does a pretty
good job now in optimising tail calls; even indirect ones on ix86
