<div>This patch adds a new option to the erlang:system_monitor
BIF, allowing to subscribe monitor process to the
long_message_queue events. It should be really helpful when
investigating architectural bottlenecks, as well as a part
of regular logging procedures. </div>
<div><br>
</div>
<div>Few comments about the implementation:</div>
<div>- Monitor messages are generated once the message gets
appended to the receiver's message queue. </div>
<div>- For a certain process - monitor message can be
generated only once after exceeding a pre-configured
threshold. Erlang VM will resend the monitor message only
once the process mailbox size gets below the limit and
exceeds them again.</div>
<div>- Info list of the monitor message currently contains
only receiver's message queue length. If you have any ideas
on what might be useful to put there in addition to the
mailbox size - please let me know.</div>
