Please add a test, you can ask it to skip if there's not enough memory on the host: node/test/parallel/test-tick-processor-arguments.js Lines 8 to 9 in eb8a51a

This reverts c380ee6. uv_fs_write returns an int, so it is not possible to ask it to write more than INT32_MAX. Instead, validate 'length' is an int32 in JS to avoid the assertion failure.

I think #36643 should be reopened. It's not possible that the reverted commit fixed it.
Repro:
That errno -2147483648 is 2147483648 wrapped around.
I didn't add a test for this because the test would require allocating a 2 GB buffer.cc @RaisinTen
