POSIX is explicit this works:
Attempts to use tcsetpgrp() from a process which is a member of a
background process group on a fildes associated with its controlling
terminal shall cause the process group to be sent a SIGTTOU signal. If
the calling process is blocking or ignoring SIGTTOU signals, the process
shall be allowed to perform the operation, and no signal is sent.
