[IPython-User] Fwd: Stdout not immediately appearing using %run in IPython 0.10.1

[Fernando Perez]

Strangely lost message from Wes to the user list, no idea what's going
on.  I'll reply separately, this is just so his original message goes
through unmodified.

Cheers

Hey Fernando-- just curious, did you receive this message from the
mailing list? For some reason I think the scipy.org server
periodically rejects messages I send (like I don't see this one on the
gmane web mirror, strange).

I've been having this problem both in IPython 0.10 and 0.10.1 using
EPD 6.2 on AMD64, Ubuntu 10.04.

Here's  an example script:

import time

def f():
   print 'a'
   time.sleep(1)
   print 'b'
   time.sleep(1)
   print 'c'
   time.sleep(1)
   print 'd'
   time.sleep(1)
   print 'e'

if __name__ == '__main__':
   f()

In [1]: run foo2.py <-- OUTPUT APPEARS IMMEDIATELY
a
b
c
d
e

In [2]: import numpy

In [3]: numpy.array? <-- press q right afterward

In [4]: run foo2.py <-- NOTHING APPEARS UNTIL %run has completed
a
b
c
d
e

I've only noticed this problem on Linux, any clues?

Thanks,
Wes
