Hello everyone,
I have a curious problem which I'm wondering if anyone here can shed
some light on. I'm basically just following along with a guide which
is going through some of the os module, and I'm running some examples
in the python interpreter on mac os x (accessed through terminal/
bash).
Basically all I did was use os.fork() which caused this strange
problem:
Macintosh:~ $ python
Python 2.5.1 (r251:54863, Jan 13 2009, 10:26:13)
[GCC 4.0.1 (Apple Inc. build 5465)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
import os
pid = os.fork()
As soon as this returns, you have two CPython processes reading from stdin
and writing to stdout. They fight over your input and their output gets
interleaved in non-deterministic ways. Basically, you probably don't ever
want to do this.
