Succession of Patterns

Here we resume previously introduced memory analysis succession patterns series (Volume 4, page 93). We introduce a case study where Wait Chains (executive resources, Volume 2, page 147) and Swarm of Shared Locks (Volume 3, page 107) were probably resulted from Spiking Thread (Volume 1, page 305). We have these resource locks:
