Through cases of Blocked Workload when lower priority tasks hold resources but do not get sufficient CPU time to complete their work and then release those resources which are in turn being waited on by higher priority tasks.

• Seen in CPU constrained environments.

• Symptoms are similar to a latch hang.

• IGW038A messages indicating latch contention
• Generally clears once CPU load decreases

• May also manifest as slow obtain and release of latches depending on CPU conditions

This request is to :-

1) Extend PDSE_SYSEVENT_DONTSWAP ENQHOLD processing to include PDSE LOCKs in addition to PDSE LATCHes

2) Only issue IGW038A messages for resources that actually have waiters
