How can I flush stdout for a process under nohup?

Question

Is there a way to flush the buffer that nohup buffers stdout? From what I read in various places (eg. some place) is that I can modify the behaviour from within my programm. But that would be specific to each programm, and there are some where I would not want to mess with the code.

So I am looking for a general way to tell a 'nohuped' programm to flush stdout. Something on the commandline likeflush sdtout <PID>. Is there something like that? Or some sort of workaround?

It's possible the (deceptively simple) unbuffer script that comes with expect may do what you're looking for.
