Subject: lua plugin: Don't destroy interpreter early
X-Git-Url: https://git.octo.it/?a=commitdiff_plain;h=1fe028d387704d46ef777a3f47168baa2262ef78;p=collectd.git

lua plugin: Don't destroy interpreter early

If script successfully registered at least one callback,
destroying interpreter will cause Collectd crash when
that callback will be called.

Unfortunately, there is no way to unregister these callbacks
