Free as in beer. Not free as in speech and I need the latter. If you impose
any conditions on what I may do with the information I learn by looking at it,
then I can't look at it. It's simple bureaucracy: unless it's one of the OSI-
approved licences, I can't accept it on behalf of my employer.

The standard Linux malloc() is also thread-local (for the most part) during
allocation. If you're getting a 3.6x performance over it, then one of the
following must be true:
a) you've come across an extremely important improvement that others haven't
b) you've hyper-optimised for one or a few use-cases, to the detriment of the
c) you've missed something really important that has caused the others to
  require a much larger overhead.

If it is (a), it will require a full paper explaining just what that is (with
whichever protections you may want for your IP). If it is (b), it deserves a
paper explaining when it should be used and when it shouldn't. And if it is
(c), you need to know about it and fix it.
