I'm afraid I don't know about those locked files, but in any case this
sounds more like a general Cygwin question. When you press Ctrl-C or
Ctrl-\, MinTTY simply writes the corresponding control character to
the pty device connecting it to its child process. The terminal driver
normally turns that into a SIGINT or SIGQUIT, but applications can
override that, or choose to ignore signals. Also, Cygwin can't deliver
signals while a program is executing a Win32 function.
