[Spce-user] Question on concurrent_max used in domain

After some further testing it does seem like this is broken, or it is 
worded incorrectly.
concurrent_max seems to work setting the number specified to both 
inbound and outbound
so setting concurrent_max to 2 on a domain or subscriber allows
2 calls in and 2 calls out simultaneously for a total of 4 concurrent calls.

Is there anywhere I can set a limit on all concurrent calls regardless 
of if they are inbound or outbound?
I just need to limit a domain to a finite number of concurrent calls 
regardless of if they are inbound or outbound.
