We need to find a minimal patch that fix the problem.
Cat you try the attached patch?

I applied the patches to the 0827 version again (had to do the sendbackup-dump.c patch by hand since the patch was for another version). I ran a full backup again, and all 3 file systems were successful and there were no "strange" messages. The debug logs show these lines:

1251756671.281800: sendbackup: fd 3 is set with O_NONBLOCK before dup2
1251756681.457166: sendbackup: Index created successfully

This is looking like some bizarre instance of the observer effect!
