Module `STM_thread`Source

Module for building concurrent STM tests over Threads

Context switches in Threads may happen

at allocations and
at safepoints https://github.com/ocaml/ocaml/pull/10039.

This module relies on Gc.Memprof support to trigger more frequent context switching between threads at allocation sites. This works well in OCaml 4.11.0-4.14.x and 5.3.0 onwards where Gc.Memprof is available.

In OCaml 5.0-5.2 without Gc.Memprof support the context switching at allocation sites will be inferior. As a consequence the module may fail to trigger concurrency issues.

Context switches at safepoints will trigger much less frequently. This means the module may fail to trigger concurrency issues in connection with these. Consider yourself warned.
