OT: Evidence of A Intel Virtual Memory Vulnerability

[Jack Stouffer via Digitalmars-d]

The gist of the story is that an Intel vulnerability is requiring 
OS vendors to institute Page Table Isolation in their kernels. 
This fix has an _across the board_ 5-7% slowdown on Intel chips.

Worse yet, programs which do lots of syscalls will see around a 
30% slowdown or more, including compilation.

AMD is not effected.
