I don't see anything wrong with your code, so it should work. If you can't get it working, one way to work around it would be to create a pipe to be used by your reading thread and the thread that prepares things for writing, and add the pipe's reading end to your select set. Then, when the other thread has prepared data to write, it just sends something on the pipe, your reading thread gets woken up from the select, and it can then do the writing. Depending on how often there is data to read or write, this could also be more efficient.
