It's more interesting, than that.
The events are as follows:
1. Start mintty.
It starts bash and present you with a command prompt.
[]$ ps
PID PPID PGID WINPID TTY UID STIME COMMAND
4212 1 4212 4212 cons0 1004 16:58:35 /usr/bin/ps
16116 1 16116 16116 ? 1004 16:58:28 /usr/bin/mintty
I 8708 16116 8708 6208 pty0 1004 16:58:28 /usr/bin/bash
2. Execute "/c/WINDOWS/system32/ping.exe -t localhost"
It starts YET ANOTHER bash, not visible to ps, even in -W mode, but clearly
spotted in task manager.
Module: bash.exe
Full path: C:\Programs\CygWin\bin\bash.exe
PID: 15688
Parent PID: 6208 (bash.exe)
Priority: 8
Threads: 2
3. Now, if you Ctrl+C, the console hangs.
If you let it sit down and think a bit, the iterrupt will be delivered to ping
and it get out of the lockup.
Going to grab a snapshot and see if it affect anything.
P.S.
Standard console doesn't exhibit the lockup.
