Win32-specific module with memory and CPU time limits
The Win32-specific implementation of call() and friends now lives
in module win32, looks clean and in addition is able to enforce memory
and CPU time limits on NT kernels, in particular on Windows 2000 and up
asking the system to terminate the process as soon as or (in the case
of CPU time) almost as soon as the limits are broken. According to my
observations, malloc() in the limited process does not return NULL
when memory usage is close to the limit and instead crashes the process
(which Upreckon happily translates into 'memory limit exceeded').
The catch is that the module is not actually used yet; coming soon.
