--- Comment #40 from Zebediah Figura <z.figura12 at gmail.com> ---
Ultimately, if we really want to pursue making direct syscalls work (and I
still wince that the idea isn't immediately thrown out as absurd), I think
we'll need to start talking to the Linux kernel about giving us a custom
interface that makes it easy and performant.

I'm not a kernel developer, but I'll just throw some things out here. Knowing
that we're going to have to start introducing some universal thunking at PE <->
Unix boundaries anyway (for e.g. ARM64's x18), the most ideal thing would be to
make part of that a way to toggle whether syscalls should be trapped or not.
That toggle of course wouldn't be able to involve a syscall itself; it would
probably have to point to some bit of global memory that is registered at an
early point in the process.
