Possible - but you should avoid this as much, as possible. Because
hardware interrupts are asynchronous and calling services, which was already
called and not finished, may mess anything. For example, almost all DOS
functions are not reentrant.

This should be safe. Especially, with CTMOUSE - I pay much attention to
make CTMOUSE safe in sense of reentrancy.
