xxh32 leaves open handle

[urugator]

Hi, xxh32 (not sure if specifically this function or the lib in general) seems to be leaking some resources. When used as part of jest tests, it randomly causes:
"Jest did not exit one second after the test run has completed."
When executed with --detectOpenHandles:

Jest has detected the following 1 open handle potentially keeping Jest from exiting:


    > 1 | import { xxh32 } from '@node-rs/xxhash';
        | ^
      2 | xxh32('foobarbaz');
      3 |

      at Runtime._loadModule (../../node_modules/jest-runtime/build/index.js:1218:29)
      at Object.<anonymous> (../../node_modules/@node-rs/xxhash/index.js:64:29)
      at Object.<anonymous> (test/foo.spec.ts:1:1)

This issue was originally reported as part of @nestjs repo:
nestjs/nest#11072

While at it, hope it's ok if I mention another issue that prevents adoption by the same lib, which deals with cross-platform development: nestjs/nest#11071
Could you perhaps clarify if this is expected behavior? Is the generated lockfile platform specific? Is this workflow possible/supported? What would be the correct/intended way to handle such situation? Thank you.
