OpenBSD: crashing

I think I've fixed all the problems with rtl_fm.  It does not use the async helper functions any more.  For my purposes async mode is broken.  No clue what happened, but when you re-turn it freezes up on rtlsdr_demod_read_reg(dev, 0x0a, 0x01, 1); line 476 of librtlsdr.c. The new code is still multithreaded and should be just as fast. My patch is at https://github.com/keenerd/rtl-sdr It would be nice to hear if this fixes the OpenBSD problems, and a confirmation that the new code still runs under windows. -Kyle http://kmkeen.com
