You're reinventing thread-specific data. It even comes with destructors.

...
The problem with thread-specific data is that it gives a back-door path
for bugs, just the same as global variables can. If the data is really
related to one instance of an object, and somehow the thread gets passed
another instance of the object and calls a method, you've now got ugly
dependencies that will bite you.

Thanks to everyone who replied. Thread-specific data is what I was
looking for. Wish the scope of thread-specific data was limited
similar to the scope of static variables.
It can be if you scope the key (which you can do with a static).
