There is no way to prematurely stop the solver but cancellation.
In order to implement that feature the solver routine containing a
main loop should be able to receive signals asynchronously posted
from other processes. A complete implementation would be very
platform specific, so the only thing which might be implemented is
a user-exit routine called, say, whenever the mip solver finishes
processing a node subproblem.
