In this particular case, the destructors vector used by
QThreadStorageData has already been destroyed, yet a new QThreadStorage
is being allocated. This can only happen during global destruction, at
which point we assume that there is only one thread. In order to keep
QThreadStorage working, we need somewhere to store the data, and the
best place we have in this situation is at the tail of the current
thread's tls vector. The destructor is ignored, since we have no where
to store it, and no way to actually call it.

After commit 4363d4eebce4afd2ce3b3d6da205f8037357099a, createUuid()
would create a QFile, open it, read from it, and destroy it. This
resulted in a pretty serious performance regression (report says around
2000 times slower, I measured 3600 times slower on my machine).
This change creates one QFile per thread (since QFile is not thread
safe) and leaves the file open until the thread exits (at which point
QThreadStorage deletes the QFile).
This approach is around 600 times faster than the current code, which is
around 6 times slower than the original. Unfortunately, it is not
possible to restore the original performance without reintroducing the
problems that the commit mentioned above had fixed.
Benchmark is included.

Set various pragmas and defines to tune the hybrid allocator.
Performance test was the time takes to allocate or deallocate as
appropriate 1,000,000 times from a set of 100,000 pointers, selected at
random, with sizes generated randomly with min 2, max 5960, avg 46.
The function was exp(8 - log(2 + rand(0..1023))) * rand(1 or 4).
The following parameters were chosen:
* pragma arm, for ~1.2%
* pragma Otime, for ~3%
* pragma O2, already the compiler default, just to be sure
* all possible slab sizes enabled, for ~1%
NB Disabling BTrace would also gain ~1.5%, but that seems like a bad
thing to do. Not done.
