I can well see a vendor trading scalability for experimental non standard TCP
algorithms that tend to be disabled anyways.
Or allocating separately if you prefer that. In theory it may be even
possible to change the slab cache size at runtime, but that could get tricky.
It would be nice to minimize this if possible, but
keep in mind that dynamic allocation of memory (and freeing
it) is among the costliest performance hits we take..
