hm, FYI, these bits caused widespread scheduling-while-atomic 
problems on most of my test-systems:

BUG: sleeping function called from invalid context at net/core/sock.c:1851

Please give this patch a try.

Started testing it - thanks David!

With several dozen test-cycles (and [a]x25 reactivated) it looks 
good and stable so far.

Thanks,
