>why not allow syscalls to be optimized in the same way intra-VM-Calls are?

It requires more complex asm code so I'm just skipped it for first time

>Next thing I'm wondering why we need the jump tables built into the VM. Can't
we just build the jused array in the first pass?

"switch" statements may generate jump tables (stored in data segment), so jump
address can be calculated during runtime execution only - i.e. not all jump
labels can be referenced(->detected) during compilation passes
