 It seems that the invocation of magic commands (e.g., ?,
 %pcat, etc.) causes ipython to delay writing output
 generated by any subsequently executed code to the console until the
 entire block of code in question is run. For instance, if one runs the
 following code

 {{{
 import time
 for i in xrange(3):
     print i
     time.sleep(2)
 }}}

 from within ipython, accesses the help system with the ? command, and then
 attempts to run the above a second time, one will notice that no output is
 written to the console until the script finishes running.

 I have observed this behavior using both ipython 0.8.2 and the latest
 development revision (104) on Linux with Python 2.5.2 (in both cases, I
 removed ~/.ipython prior to testing the behavior).
