yes; "from x import y" does an ordinary import of "x" under the hood.

not really, unless you're willing/able to refactor the module you're
importing.

several seconds? sounds bad. what does the following script print on

import time, subprocess, sys
t0 = time.time()
for i in range(10):
subprocess.call([sys.executable, "-c", "pass"])
print time.time() - t0
