Exception with (too many?) folders

[geotre]

Minimal reproduction:

import fswatch

var monitor = newMonitor(latency=0.01)
monitor.set_recursive true
monitor.add("test_files")

proc callback(eg: EventGroup) =
  for e in eg:
    echo "Event: ", e.kind

monitor.setCallback(callback)
monitor.start()

Create a folder containing some folders and run:

mkdir test_files
for i in `seq 10`; do mkdir "test_files/$i"; done
nim c -r test.nim

Yields this result:

Error: unhandled exception: index 101 not in 0 .. 100 [IndexError]
