python BPF class destructor

Hello,

I am trying to add bpf_obj_pin support and want to remove the pinned bpf table when python BPF class is destroyed. I have written the bpf_obj_pin deletion code in BPFModule destructor. However, currently it isn't called at python BPF class destruction.

cc/bpf_module.h have a destructor (BPFModule::~BPFModule()), which is only called in case the BPF code fails to compile. Shouldn't python BPF class need to have a destructor (**del** or **exit**) which should call the cc/bpf_module.h destructor at exit?

diff --git a/src/python/bcc/**init**.py b/src/python/bcc/**init**.py

or are there some cases where python BPF code exit but we don't want to destroy BPFModule?
