Theoretically, the TLAs could have bugs and need further testing.  In 
practice, they generally seem better than the last stable release, as they 
mostly contain bug fixes.  I personally believe that the recent TLAs have 
been very good and would use them over 1.3.7 (quite a few bug fixes have 
been made since then).  However, the developers have indicated that the 
official, stable 1.3.8 release, from recent TLAs, should be right around 
the corner.

Disabling direct-io will probably lower performance but should have no 
other observable effect, as far as I understand.

Thanks,
