sigaction(2) says:

    The affected system calls include open(2), read(2), write(2),
    sendto(2), recvfrom(2), sendmsg(2) and recvmsg(2) on a communications
    channel or a slow device (such as a terminal, but not a regular file)

so I guess a SIGWINCH during the open(2) for ~/.bash_profile, etc. can
still get interrupted.
