Hi Hasmik, you wrote:

I guess it would, but first the default signal handler terminates it.
You should ignore SIGINT or install a handler, maybe  which writes "ouch!"
to fd 2 (stderr). After ^c, (my) programs by default die under Unix, too,
and so does tclsh. And I'm pretty shure tclsh retries after EINTR.
If (debugger == gdb), then under Unix, it doesn't pass SIGINT to the
debuggee by default. Check output of "info signals" on cygwin32 and Unix...
