-package tcell
-
-// The Darwin system is *almost* a real BSD system, but it suffers from
-// a brain damaged TTY driver.  This TTY driver does not actually
-// wake up in poll() or similar calls, which means that we cannot reliably
-// shut down the terminal without resorting to obscene custom C code
-// and a dedicated poller thread.
-//
-// So instead, we do a best effort, and simply try to do the close in the
-// background.  Probably this will cause a leak of two goroutines and
-// maybe also the file descriptor, meaning that applications on Darwin
-// can't reinitialize the screen, but that's probably a very rare behavior,
-// and accepting that is the best of some very poor alternative options.
-//
-// Maybe someday Apple will fix there tty driver, but its been broken for
-// a long time (probably forever) so holding one's breath is contraindicated.
