It seems to use a Linux specific syscall to force all the sibling
threads to flush their ICache for background JIT purposes. We don't
have anything like that to my knowledge. But it looks like we can
comment out this code and make CanFlushICacheFromBackgroundThreads
return false. I will test and commit if that works OK.
