Research direction
Start with the NUMA implementation of static_thread_pool; the issue names no specific file or test. Reproduce repeated dlopen/dlclose of a shared object using stdexec and investigate shutdown behavior. Done means teardown avoids the unbounded memory leak without reintroducing the static-initialization-order-fiasco bug.
Written by the indexing model from the issue text.
Description
#1369 "fixed" a static-initialization-order-fiasco bug in static_thread_pool teardown by constructing a global std::vector and never destroying it. if stdexec is used in a .so that is repeatedly loaded and unloaded with dlopen/dlclose, it will leak an unbounded amount of memory.
