Results of 20070419 testing

[Mike Mason]

I'm working on a fix for the socket test failure.  Should be checked in today.  

The problem is that do_sock_write() is called in one place instead of two as of 2.6.19 and, thus, gets optimized away. Same for do_sock_read().  Is there any way to mark a symbol so that the compiler doesn't optimize it away?
