Can't use pycryptodome before "import psutil" due to "Unknown identifier: PyObject_GetBuffer" #555
Description
pycryptodome cannot be imported and used before a python statement "import psutil" which is rather odd!
if not "import psutil", will run into a error like:
[ERROR] org.example.embedding.test.EmbeddingTest.testFail -- Time elapsed: 43.38 s <<< ERROR!
AttributeError: AttributeError: UnknownIdentifierException: Unknown identifier: PyObject_GetBuffer
Java stack trace:
com.oracle.truffle.api.interop.UnknownIdentifierException: Unknown identifier: PyObject_GetBuffer

test
mvn testthere are two tests, the first one will run "import psutil" before import Crypto, and it passes!
the second one, will not run "import psutil", and there it fails.
