[Barebone] unable to insert page table mapping

[Manouchehri]

When using the backbone backend with a virtual Raspberry Pi 4 on AVH, I run into this error when attempting to use Memory.scanSync:

Error: unable to insert page table mapping; please file a bug
    at <eval> (<input>:3)
    at eval (native)
    at <anonymous> (/frida/repl-1.js)
    at evaluate (/frida/repl-1.js:57)

Script:

const pattern = '35 2e 31 35 2e 30 2d 31 30 31 32 2d 72 61 73 70 69'; // 5.15.0-1012-raspi

for (const r of Process.enumerateRanges('r--')) {
  console.log(JSON.stringify(r, null, 2));
  const matches = Memory.scanSync(r.base, r.size, pattern);
  console.log('Matches:', JSON.stringify(matches, null, 2));
}

Adding a try/catch block results in a very slow process filled with mostly errors. I guess this is related to #506?
