Alternative to SoDB::doSelect()

Since SoDB::doSelect() is obsolete, what is the alternative mechanism in Coin to handle synchronous I/O while Coin continues to handle sensor events, rendering, etc?

According to https://bitbucket.org/Coin3D/coin/commits/35ca6c1bfe89f13ab96808b02b03d94fff8cb19a doSelect() has never worked.

I don’t understand the select() system call. I guess you could do the I/O in a separate thread? Note that if different threads need to access the scene graph, you must use the locking functions from SoDB and configure Coin for multi threading.
