    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.
