Memory leak

[kseyhan]

There is a massive memory leak when using those nodes on my computer running linux.

Before running the supir workflow from the examples folder:

$ free -h
total used free shared buff/cache available
Mem: 62Gi 17Gi 6,9Gi 2,3Gi 41Gi 44Gi
Swap: 8,0Gi 7,9Gi 95Mi

after running the workflow:
$ free -h
total used free shared buff/cache available
Mem: 62Gi 37Gi 2,2Gi 2,2Gi 25Gi 24Gi
Swap: 8,0Gi 8,0Gi 396Ki

and it simply stays like this.

the memory does not get released even after loading other workflows and when switching back and forth those nodes here keep more and more ram hostage up to the point that the server process is crashing because no more memory can be allocated at some point.
