static ctors in shared libs

[bitwise via Digitalmars-d]

I've been doing some work on shared libraries for OSX, and have 
come across a potential problem, which I'm not sure what to do 
with.

Currently, when a thread is spawned, that thread calls all the 
TLS ctors, then runs the thread entry point function, and finally 
calls the TLS dtors before the thread terminates.

Example, for windows:

https://github.com/D-Programming-Language/druntime/blob/15a227477a344583c4748d95492703901417f4f8/src/core/thread.d#L236

So, the question is, how do dynamic libraries interact here?

Example: A dynamic library contains D modules with TLS ctors. If 
I start a few threads, and then load a dynamic library, shouldn't 
the TLS ctors in the dynamic library be called for each running 
thread? If my assumption is correct, the next question is, how do 
you do this?

I don't think you can hijack each thread and have it run the TLS 
ctors, and you can run them all from the thread loading the 
shared library because of synchronization issues. So what's the 
solution? Should TLS ctors in dynamic libraries simply be 
specified not to run, or could they somehow be run lazily at the 
first TLS access in a dynamic library?

Any thoughts on this would be appreciated.

Thanks,
