Gambit does not use Cheney on the MTA, mainly because it interferes
with the implementation of unrestricted calls from Scheme to C and
from C to Scheme. Gambit's implementation of continuations is done
with a lazy copy of the captured continuation. The performance is
quite good... on the two call/cc intensive Gambit benchmarks (ctak and
fibc) Gambit outperforms Chicken. Note also that Gambit's thread
system is based on continuations, so it is important for continuation
operations to be efficient.
