New test io-53.18 adapted from demo script in [32ae34e63a]. This test
segfaults without changes to source code. This checkin also contains a revised implementationf of [chan postevent] that stops calling Tcl_NotifyChannel() directly, and queues an event to do it instead. This stops the segfault, but causes tests iocmd-31.[67] to fail. Need advice on whether that matters.
