Is print thread safe?

[Steven D'Aprano]

Specifically for Python 2.6 and 2.7, but answers for 3.x appreciated as 
well.

Is print thread safe? That is, if I have two threads that each call 
print, say:

print "spam spam spam"  # thread 1
print "eggs eggs eggs"  # thread 2

I don't care which line prints first, but I do care if the two lines are 
mixed in together, something like this:

spam spaeggs eggs m seggspams


Does print perform its own locking to prevent this?
