i'm not sure why you mention thread creation and freeing. The syslet/threadlet code reuses already created async threads, and that is visible all around in both the kernel-space and in the user-space syslet/threadlet code.
While Linux creates+destroys threads pretty damn fast (in about 10-15 usecs - which is roughly the cost of getting a single 1-byte packet through a TCP socket from one process to another, on localhost), still we dont want to create and destroy a thread per request.
