Odds are it is that there's terminal output for the background process

NOT a character btw, just any output, then the OS puts you on hold so it can do its thing.

To catch a signal, it is just like in C http://stackoverflow.com/a/35687472/1457000

simplest case:

import core.stdc.signal;
signal(SIGTTOU, SIG_IGN); // ignore the output thing


and see what happens next

I tried with signal, but didn't catch SIGTTOU, it seems that spawnProcess with `bash -i -c` will signal with SIGTTIN.

When I catch SIGTTIN with:

 extern(C) void sig_hand(int signal) nothrow @nogc @system {
    import core.stdc.stdio: printf;
    printf("signal %d catched!\n", signal);
 }

I get an infinite loop of

signal 21 catched!
signal 21 catched!
signal 21 catched!

Not sure how to handle that. Maybe I can't use `bash -i`.
