max_iter = float('inf') looks wrong

[kmike]

it is used in memory_usage function like this:

    if timeout is not None:
        max_iter = int(timeout / interval)
    elif isinstance(proc, int):
        # external process and no timeout
        max_iter = 1
    else:
        # for a Python function wait until it finishes
        max_iter = float('inf') # <--------------------------

    if isinstance(proc, (list, tuple)):
        # ... (snip)
    else:
        # external process
        if proc == -1:
            proc = os.getpid()
        if max_iter == -1:
            max_iter = 1
        for _ in range(max_iter):   # <----------------
            ret.append(_get_memory(proc))
            time.sleep(interval)
    return ret

range(float('inf')) is an error, and max_iter is not used for anything else here.

Thanks Mikhail, should be fixed now
