Memory leaks seem easy to detect, however, building with KMEMLEAK debugging on can take up to 50-67% of system time, as I've noticed a couple of days ago ... It is obviously incurring some overhead. I did not expect a kernel compilation as computation-heavy process to have such an impact from memory object debugging.
