Customer needs to map up to one million shared mutex/shared condvar per shared memory segment under z/OS Unix.

Customer running an app that hit an internal limit (JRSMCMaxCntSeg 65535 decimal)) creating shared mutex and shared convars. Discussions with the customer indicate that there is a need to support one million of these type of structures. This will require use of above-the-bar (64 bit) storage. Customer noted that this limitation does not exist on other UNIX platforms (Sun AIX) where their code is already running. Lack of z/OS UNIX support for this means thay cannot directly port this application to the z/OS platform.
