Potential Memory Leak

[nilmerg]

A query that is repeatedly executed, and not re-constructed before every execution, seems to cause a memory buildup that ultimately leads to memory exhaustion after some time.

Not sure if this is really only caused by repeated execution. Icinga DB Web splits command action targets into chunks and during testing a memory overflow was triggered by a bulk operation on +10k objects. The initial (and only) fetch seems not to be responsible, it's the evaluation of the results afterwards which triggered it.
