https://github.com/lanl-ansi/Alpine.jl/issues/223 rises from the grave. I don't remember if we support user-defined functions, but we should at least throw a nicer error message: ```Julia (alpine) pkg> st Status `/private/tmp/alpine/Project.toml` [07493b3f]...

The asynchronous solver currently uses multiprocessing. This causes a lot of excess RAM usage because we need N copies of the full problem. If we introduced a lock to every...

Refactor constraint deletions and GRBupdatemodel

The MOI wrapper eagerly updates the row indices of constraints in a model upon deletion: https://github.com/jump-dev/Gurobi.jl/blob/38464c27b96e9818257b22c61d2458890957d0fe/src/MOI_wrapper/MOI_wrapper.jl#L2115-L2129 We should instead do what we do for variables and lazily delay the update...
