Graham Dumpleton: Load spikes and excessive memory usage in mod_python.
Database access (and some other Python modules) causes threads to lock so only 1 thread in process is active. This causes major performance penalty - all threads in process are waiting while SQL query is executing.

If a database adapter or other third party C extension module doesn't unlock the GIL before going into a blocking operation then that module is fundamentally flawed and it should be reported as a bug in that module. None of the major database adapters available have this problem as far as I am aware, so please be more specific about which extension modules you believe are broken.
