I've seen this in valgrind for as long as I've been working on Numba / llvmlite, and I always assumed it was because of the cpuid instruction writing a value...

Are you having memory or performance issues when using llvmlite? I'm concerned that adding `__slots__` might break use cases where additional attributes are attached to instances, and add additional maintenance...

Thanks for the PR! I'm curious about > In my own compiler's codebase, ... Is there any public info about your compiler?
