Thanks, I plan to implement mutex using native CreateMutex soon but this
problem will appear then if we try to use shared memory in DLL loading
(and this includes managed_shared_memory in Windows!).
I'm afraid I have no easy fix for this, because I have no other way to
obtain a reliable bootup timestamp (which I need to obtain kernel
lifetime for shared memory). I think you could (until we fix this) use
native windows mutexes (and maybe windows_managed_shared_memory) in
intermodule_holder. There is another advantage: the mutex/shared memory
will cleanup automatically on process exit or crash.
