| Now, what I don't like about my proposal and your proposal is | that the user has to be aware of OS threads when making | foreign calls by wrapping it in "threadSafe" or adding | "threadsafe" sometimes -- but maybe that is unavoidable. Actually, the proposal currently on the table, which no one has objected to, is * abolish the distinction between "safe" and "threadsafe" * make "safe" the default (it already is) So the user needs to do something special only if she wants to do something unsafe (by adding "unsafe" to the foreign import).
