Might be good idea to abstract out the try/finally idiom out.
@mateiz, any thoughts ? We have a bunch of places where resource cleanup
does not happen properly - which become relevant only when things fail.
Ofcourse, in almost all of these cases, failure usually should result in
killing the worker anyway ... but still, will be good to enforce proper
resource lifecycle.
