Two conflicting requirements there; FFI is not a particularly fast way
to access a plugin. If every cycle counts, a custom plugin Slang
section is the way to go. By all means do the initial experiments via
FFI but if you want the fastest prim access, sling dat Slang.

By the way, in the latest VMs the address of the external prim is
cached in the method lookup table. Once they are in the cache they
should be exactly as fast to get to as normal prims.
