This actually doesn't seem like a bright idea to me, considering
that this gets called when starting every request. How will you look
at me adding the transport method for writing this register? :-)
OTOH, adding such a "backdoor" to the taskfile doesn't seem very
consistent... well, I'm not excited about the whole idea conversion to
tf_{load|read}() -- it's not clear what exactly this bought us.
