Add an import timing monitor

[itziakos]

The following example will time imports

import imp
import sys
import timeit


class Loader(object):
    def __init__(self, path):
        self.path = path

    def load_module(self, name):
        if name in sys.modules:
            return sys.modules[name]
        before = timeit.default_timer()
        try:
            module_info = imp.find_module(name, self.path)
            module = imp.load_module(name, *module_info)
        finally:
            after = timeit.default_timer()
            print('{: <50s} {:.5f}s'.format(name, after - before))
        sys.modules[name] = module
        return module


class Finder(object):

    def find_module(self, name, path=None):
        return Loader(path)

sys.meta_path.insert(0, Finder())

It would be nice to have it as a pikos monitor
