Hi Travis, The current MR with my WIP is at https://gitlab.haskell.org/ghc/ghc/merge_requests/1224 This should build without a problem (on Windows, haven't sorted the Linux build failures yet). The threaded version passes the testsuite (i.e. -threaded +RTS --io-manager=native) but the non-threaded version has proven tricky to support correctly. That one still has a deadlock that I am debugging (though I have made significant progress since I last updated that MR). I will push the updated code this weekend. Though I'm afraid that based on it not getting any review of the design so far and my current work commitments I won't be able to get this done for GHC 8.10. So I will punt it to GHC 8.12. The MR contains a list of TODOs in case you're wondering what's left on it. Thanks, Tamar On Tue, Sep 24, 2019 at 11:39 PM Travis Whitaker wrote:

Hello Haskell friends,

Even though I no longer work at a Windows shop, I've been watching https://gitlab.haskell.org/ghc/ghc/issues/7353 with great interest. Last I knew Tamar Christina was heroically hacking away on a new IO manager for Windows.

Although my low-level Windows knowledge is likely insufficient for me to contribute significantly, I'd be very interested in testing the new IO manager and helping with debugging in any way I can. How might one go about building a GHC with this new Windows IO manager?

Thanks, as always, for all your hard work,
