Re: Multithreading in GR blocks

[Sylvain Munaut]

The m_finished thing only works if you're not using any blocking calls.

But you're using `accept` and `recv` etc ... all calls that can block
forever until they get something.
You need to use `select` on the file descriptors while waiting for
events / data and set a timeout on that select so your code has a
periodic opportunity to check the m_finished flag.
