+// Close tears the pty down without waiting for it: the teardown runs on a

+//
+// It has to, because ClosePseudoConsole can block for a long time: before
+// Windows 11 24H2 it waits for the console host to exit, and since closing
+// only delivers CTRL_CLOSE_EVENT to the attached client without terminating
+// it, a client that keeps running (git still computing an expensive diff, a
+// pager waiting for input) keeps the host — and with it ClosePseudoConsole —
+// alive arbitrarily long. Close is called while holding the global PtyMutex
+// and while the task's onDone once is executing, where blocking wedges every
+// subsequent task for the view (and with it the UI), so none of this may
+// happen on the caller's thread.
+//
+// Within the teardown, the pipe ends must be closed before the

+// is broken. The background waiter's closeHpc may already be wedged in such
