# @human-monitor-command:
#
# Execute a command on the human monitor and return the output.
#
# @command-line: the command to execute in the human monitor
#
# @cpu-index: #optional The CPU to use for commands that require an implicit CPU
#
# Returns: the output of the command as a string
#
# Since: 0.14.0
#
# Notes: This command only exists as a stop-gap. It's use is highly
# discouraged. The semantics of this command are not guaranteed.
#
# Known limitations:
#
# o This command is stateless, this means that commands that depend
# on state information (such as getfd) might not work
#
# o Commands that prompt the user for data (eg. 'cont' when the block
# device is encrypted) don't currently work
