Check address space timeout

When an address space is launched for a client, and it has completed its current function, the address space is waiting for TCP/IP communications from the peer. In line with this, the client address space might be subject to an s522 abend if waiting longer than the active site settings for job wait time. The job wait time is controlled by the JWT parameter of the SMFPRMxx member, but might also be set to never time out by the site settings for MAXCPUTIME in the site's BPXPRMxx member. Set these parameters as needed by the site.
