[systemd-devel] Can udev assist?

I have a script that creates a partition (using pyparted) and then tries 
to format it (using mkfs.ext4). Most of the time this works OK. However, 
sometimes the format fails because it can't find the device. There seems 
to be a race condition due to a delay between creating a partition and the 
device node in /dev being created.
Is there a tool in udev or udevadm that can help my script know when it 
safe to proceed?
