I made micro benchmark of Boost.Coroutine some time ago. I was able to 
run 400k coroutines in one thread, each had 10KiB of stack (~3.8GiB was 
consumed only by stacks). I used simple allocator for stacks:
     return last_free += allocation_size;
Environment was: Windows 7 x64, MSVC2010SP1 x64, Boost 1.53. System had 
6GiB of RAM, part of which was consumed by OS and background programs. I 
think with proper tuning it is possible to launch more coroutines on 
that system.
