Deallocate JIT code on FastFn drop about lineiform

[ohAitch]

Also we don't have any multi-threading support yet lol.

I imagine the FastFn is as Send and Sync as the input closure?

I meant more that the fact that FastFn doesn't implement Send+Sync means that there are no cases in which a closure is being dropped while we are compiling other closures or running it. I think we'd have to worry about that in the event of e.g. #12 being implemented; it'd have to make sure to use reference-counted closures in order to make sure that everything stays alive while it is doing work on another thread, for example. That would have to add Send+Sync(?) bounds to

lineiform/lineiform/src/lib.rs

Line 103 in 4a104c9

pub fn speedup<F>(&mut self, f: F) -> impl Fn(A)->O where F: Fn(A)->O {

or something in order to make sure the closure is safe to access from whatever async worker thread, but not this work, and I'm not sure if it makes sense to make FastFn itself Send+Sync if we don't need to either.

Basically I was just being cheeky and the fact that we aren't caring about multithreading at all currently makes this easy.
