Argh! The patch was still broken even after this fix.
Apparently when I tested my taskqueue solution I forgot to do a make
installkernel. For some reason the taskqueue approach deadlocks my
server at home under normal conditions. Therefore I have reverted the
patch to use the simple return. I still don't think this is the right
solution, but I don't have time to completely figure out what is going
on right now.
Again, sorry for the mess!
