Yep, if programmers can't be bothered to read a few lines of manpage before using a new function as distinctly special as signal()/sigaction(), then I think there is no help in sight. But on the other hand, the signals API might be a problem. Signals aren't exactly praised as a marvel of engineering. There probably is a need for something as low-level as that in some cases. But in the common case an API that just asynchronously sets a volatile flag when a signal is received, should be sufficient. Calls to "slow" devices are interrupted and return EINTR anyway.
