@doc Set options for child process of alcove control process



`flowcontrol' enables rate limiting of the stdout and stderr of a child

process. stdin is not rate limited (default: -1 (disabled))



• 0: stdout/stderr for process is not read



• 1-2147483646: read this many messages from the process



• -1: disable flow control



NOTE: the limit applies to stdout and stderr. If the limit is set to 1,

it is possible to get:



• 1 message from stdout



• 1 message from stderr



• 1 message from stdout and stderr



`signaloneof' delivers a signal to any subprocesses when the alcove

control process shuts down (default: 15 (SIGTERM))
