== Check Daemon status

To get a list of running Daemons and their statuses, use the `--status` command:

----
$ gradle --status
----

----
   PID STATUS   INFO
 28486 IDLE     7.5
 34247 BUSY     7.5
----

Currently, a given Gradle version can only connect to Daemons of the same version.

(where to execute it), and a P (the rights and resources to execute
it). When an M stops executing user Go code, for example by entering a
system call, it returns its P to the idle P pool. In order to resume
executing user Go code, for example on return from a system call, it
must acquire a P from the idle pool.

All `g`, `m`, and `p` objects are heap allocated, but are never freed,
so their memory remains type stable. As a result, the runtime can
