    When python is cross-compiled for android with --enable-shared, the following error occurs:

    # python -c "import socket"
    Fatal Python error: PyThreadState_Get: no current thread

    This also occurs when importing subprocess, asyncore or asyncio but not when importing posix (not a shared library). This is fixed by building python without soname versioning, although I have no idea why a problem with the android loader would cause this error.
    Patch attached.

    Some references to the android loader and soname versioning:

    Python builds and runs fine on android without this patch. I cannot reproduce the 'Fatal Python error: PyThreadState_Get: no current thread' abort either.

    Closing the issue.
