In particular, what can be done from a signal? More accurately, if I can guarantee that an allocmem was not in process when I get a signal, can I call allocmem from a signal routine? Can I call dos.library from a signal handler? What can be called from the input.device feed chain? Can a input.device routine call both allocmem and sendmessage? Can it call dos.library?
