Based on discussion in eileenmcnaughton/nz.co.fuzion.omnipaymultiprocessor#30 - anonymous sessions via webforms are not stored in drupal session table before navigating to the payment page, hence after returning from the site, the session variables eg return urls are lost.
This change follows the same exit protocol as
drupal_exit()
which commits the session before exiting.
