Review Comment:
~~Pthread is joinable by default. Without a `pthread_join`, resource leak
happens.
See `man 7 pthread_detach` for remedies.~~
~~We need to check every `celixThread_create` to make sure either
`pthread_join` or `pthread_detach`~~
I am happy to know I was wrong:
`celix_framework_cleanupBundleLifecycleHandlers` calls `celixThread_join` on
these handlers. However, a problem remains:
Note that `celix_framework_cleanupBundleLifecycleHandlers` is only called by
`framework_shutdown`. What if I keep starting/stopping bundles so that resource
consumption keeps growing?
