Thanks!

This needs much modification for the cygwin console code because
the local key cache should be able to access from other process
running in the same console. This needs inter-process-communication
or shared memory.

Another simple solution is disabling cons_master_thread in win32-input-mode.
The signalling keys such as Ctrl-C, Ctrl-Z etc. never comes anyway in that
mode.

Now I'm testing this solution.
