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.
