ELF loader uses "randomize_va_space" twice. It is sysctl and can change at any moment, so 2 loads could see 2 different values in theory with unpredictable consequences.
Issue exactly one load for consistent value across one exec.

Verified the build test.
No you did not! This breaks the build.
This is really really annoying as it breaks the workflow on our side when you submit code that does not work at all.
Please go and retest all of the outstanding commits that you all have submitted and fix them up and resend them. I'm dropping all of the rest of them from my pending queue as this shows a total lack of testing happening which implies that I can't trust any of these at all.
And I want you all to prove that you have actually tested the code, not just this bland "Verified the build test" which is a _very_ low bar, that is not even happening here at all :(
