Right.

pbuf_free(head) now decently deals with the situation where the
head of a chain is removed and never used again. This seems to
be the case in all core source code.

Hmmm, yes, I can think of an approach where the queueing is expanded
to chaining multiple pbuf chains and where we need dechain() again.

For the moment, I would suggest surrounding the function with
#if 0
#endif

I have done so in CVS current.
