Just to make it clear:
1) Retrieve the page, store last edit time as TIME
2) Do something what requires user input, possibly may last few minutes
3) Retrieve the page history
<< Possible race
condition here, what if someone edit the page before step 3 and 5
4) Compare time of last edit in page history with TIME in order to
check if page was edited
<< Possible race
condition here, what if someone edit the page before step 4 and 5
5) Edit
This is not what I need ^ I need something better :-)
