Automatically restarting system calls?

I wrote a script(1) replacement in python (http://stromberg.dnsalias.org/
~dstromberg/pypty/), but I'm encountering a problem in it.
I think I know the solution to the problem, but I'd've thought python was
high level enough that this solution isn't required, so I wanted to
inquire about it here.
Specifically, the program has a signal handler for window size changes.
And if the window is resized during an os.write() (for example), I get a
python exception about needing to restart the system call.
In C, I know you're supposed to wrap your system calls with while loops
until you don't get an ERESTART, but does one really need to wrap all of
one's os.write()'s (for example) with such while loops in python?
