Due to limitations in the interaction between Julia and C, KNITRO.jl disables
multi-threading if the problem is nonlinear. This will override any options such
as `par_numthreads` that you may have set. Read [GitHub issue #93](https://github.com/jump-dev/KNITRO.jl/issues/93)
for more details.
as `par_numthreads` that you may have set.

If you are using the low-level API, opt-in to enable multi-threading by calling
`KN_solve(model.env)` instead of `KN_solve(model)`, where `model` is the value
returned by `model = KN_new()`. Note that calling `KN_solve(model.env)` is an
advanced operation because it requires all callbacks you provide to be threadsafe.
