 If you launch many connection over Tor using stem and
 launch_tor_with_config function, you'll probably have an exception like :
 '''OSError: [Errno 24] Too many open files'''

 The problem is comming from this line:
 '''torrc_path = tempfile.mkstemp(prefix = "torrc-", text = True)[1]'''

 This exception is raise because "tempfile.mkstemp" create a file
 descriptor which is never closed in '''process.py''' file.

 To properly close tempile, you have to use this correction :
 '''fileDescriptor, torrc_path = tempfile.mkstemp(prefix = 'torrc-', text =
 True)'''

 Before delete the temp file, you just have to close the file descriptor:
 '''os.close(fileDescriptor)'''
