Dear Committee, Zubin Duggal proposes to amend proposal #540, which introduced the -jsem parallelism control mechanism, so that it can avoid incompatibilities arising from different system C library implementations: https://github.com/ghc-proposals/ghc-proposals/pull/673 https://github.com/wz1000/ghc-proposals/blob/new-jsem/proposals/0540-jsem.rs... I'd like to nominate Eric Seidel as the shepherd, since he was the shepherd of the original proposal. Please guide us to a conclusion as outlined in https://github.com/ghc-proposals/ghc-proposals#committee-process Cheers, Adam -- Adam Gundry, Haskell Consultant Well-Typed LLP, https://www.well-typed.com/ Registered in England & Wales, OC335890 27 Old Gloucester Street, London WC1N 3AX, England
