[Bug report] observer crashes

[nikohansen]

speaking about creating (a large number of) nonexisting files: when calling cocoex.Observer and there exist already 999 output folders with the given result_folder name, the Python kernel crashes . Strangely enough, it happens while the folder name trailing with '-999' does not exist while '-998' does exist (hence 999 folders exist). I still suspect the string memory allocation in C as the offender in that it cannot handle more than three digits?

On macos with the current development branch.

It's a hard-coded constant so that the loop of trying new folder names stops at some point. Should we increase it? To what number?

Maybe at least to 10,000, and it should give a warning when the number module 1000 is zero?
