After some clarification and experimentation, it looks like what needs to happen is something along the lines of (setf *listener-autorelease-pool* (ccl::create-autorelease-pool)) being executed on a newly created thread and a corresponding cleanup call that should be executed before the thread terminates. Do any hooks exist for this purpose? Phil wrote:

I'm having a minor problem using SLIME with OpenMCL and it's Objective-C bridge. Specifically, I want the REPL and any other threads that get created by SLIME to process commands via OpenMCL to be wrapped by a with-autorelease-pool call (which is defined by the bridge) to prevent memory leakage when creating Obj-C objects. Where would be the appropriate places in swank-openmcl to accomplish this?

Thanks, Phil
