#42 heap space consumption

[samuel wieland]

- when the rp-proxy is used in a polling mode through the ale, the heap-space gets filled up.
- after a while, the tags do not come through anymore and apache tomcat crashes with a heap-space violation.
- cpu consumption goes up to 100% due to "failed" garbage collection.

- as can be seen on the two profiler screenshots (on the left), the heapspace gets filled up continuously. the peaks are after a polling cycle. no all of the allocated memory gets freed.
- the image on the middle shows the cpu consumption of the garbage collector.
