A modern programming language that makes developers happier.

out of curiosity, has anyone seen a discussion about why the JVM needs to keep all `Thread`'s stack memory size the same? I feel like an awful lot of performance problems could be solved if the JVM was allowed to operate with differently-sized thread stacks. For threads that simply call blocking API's and dump the result into a `Channel` (or other coroutine/threading device), I would really appreciate the ability to tell the JVM that this thing just needs maybe 8Kb of stack.

right but thats globally isn't it? What I'd like is to say that one thread pool's threads are the default and another thread pools threads have very small stacks

They should just follow Go’s example and allocate stack in 4k “stacklets”. It is a good compromise between performance you loose when you have to call external C libs (you’ll have to swtich to a real big stack) and per-thread overhead
