Preserve the preallocated last-thrown exception handle for debugger reporting when the executable allocator invokes fatal error handling from preemptive mode. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Defer MapRW fatal error reporting until after releasing the allocator lock so GC write-barrier updates can complete. Add a deterministic regression that establishes both sides of the GC/JIT deadlock. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Keep the servicing fix limited to RW mapping and metadata allocation failures. Inject failures through the real handlers, coordinate the first full GC without competing JIT work, and restrict the regression to supported Checked configurations.
