I did a performance test (included in my lib -> directory performance) 
which measures the costs of a context jump.
the result of Giovannis Boost.Context and my implementation (whic hyou 
told is slow and significant scalability problems):

CPU cycles per jump with enabled BOOST_ASSERT (1000 iterations, average 
of 10 executions):
- Giovannis implementation : 561 cycles
- my implementation: 371 cycles

CPU cycles per jump with disabled BOOST_ASSERT (1000 iterations, average 
of 10 executions):
- Giovannis implementation : 556 cycles
- my implementation: 337 cycles
