Feature request summary

Right now, under each specific arch in lcpu.h a constant named CACHE_LINE_SIZE is specified with its value set to the arch bit size (eg. for x86_64 the constant is set to 64), though this is not always the case, as this variable depends on the physical CPU that the kernel runs on. Being able to automatically detect and set this would provide performance benefits, taking advantage of the underlying hardware.
