> While working on CASSANDRA-15170 native libraries for libc functions, epoll support and openssl were observed holding gcroots to the instance class loaders when in-JVM dtest {{with(NETWORK)}} support was enabled. The solution for CASSANDRA-15170 was to disable native libraries to get everything working, but this is not ideal because in-JVM tests will not be testing the real code on that platform.
> One proposed solution from [~ifesdjeen] and [~benedict] is to introduce an additional classloader per-Cassandra version that can be used for loading native libraries and share the {{CassandraVersionClassLoader}} by each instance of that version, enabling the {{InstanceClassLoader}} to be garbage collected.
