Unfortunately this change is known to cause issues with running the Autobahn testsuite against Ratchet. Thanks to @cboden for digging into this!

I'm currently looking into providing a test case so that this is properly covered in the Stream component.

It ended up being line 90. The error I'm receiving is:

fwrite(): send of 8192 bytes failed with errno=11 Resource temporarily unavailable

On attempting to send a large amount of data (256k) to fwrite. The error simply states the buffer is full and to try again later, however the updated code now halts on all errors.

This will be fixed via #52.
