You can't call C code directly anymore.
I don't know/understand why. Probably I just don't know how a segmented
stack is implemented/structured.
If the stack is growable, I presume there's some free space anyway at
the end of it. So you are not forced to test for the stack length, so
you may call a C function and hope it will not blow the free stack left.
Probably I am wrong, but I don't know why :-)
Calling C code should still be possible, but it will involve checking for
free space on the stack and preallocating as required. A possible
optimization is to use one "C stack" per thread (with the assumption that
there's no re-entry into our code from C code).
