Thread + socket = (shared) problem? (2.048)

[Bane]

I triple checked it. 2.0.48 has problems with this, 2.040, 2.045 & 2.047 don't.

> This will throw exception on trying to create socket in derived thread. Socket created in main thread is ok. Is it some shared issue or... ? I have been trying to find something info in docs and mailing list but no result.
