title: Plugin Post Operation Lock record in Database
body: <p>I am calling a web service from my plugin whih query the CRM databae and return some data to the plugin. When I register my plugin in Post-Operation Update I am getting a time out exception which is caused by the web service trying to query the databse. When I register my plugin in Pre-Operation Update it is working like a charm. </p>
  
  <p>My Question is: DOES CRM DATABASE LOCK A RECORD ON POST OPERATION UPDATE ONLY AND NOT ON PRE OPERATION UPDATE? </p>
