I am working on a long running process that will start another process using asyncproc. After a couple of days it crashes stating that too many file handles are open. I am suspecting it is because the processes started are not being closed (based on information in osproc). I found the closed procedure in the code, but it is not exported. I didn't want to export it because I thought there might be a reason I'm missing somewhere.

Therefore, why is the close procedure not exported in asyncproc?
