This is a small library which prevents the increase of a widget/unit's life in case it is dead.
It simply runs a timer which sets it's health to 0.0 after 0.000001 seconds delay which is fairly short.
Anyway it serves as a prevention of increasing dead unit's health meaning all methods of determining whether a unit is dead should work fine now.
This aplies for 2 natives that is:
Increasing life via object editor spells probably won't be detected but i haven't tested it.
I seriously don't know if this is useful or not, i won't find myself offended if you graveyard this as it took little time to write anyway.
Here is the code(requires TimerUtils):

//************************************************************************************************************
//** PreventDeathBug (PDI) library v1.0 **
//** **
//************************************************************************************************************
//** **
//** What does PreventDeathIssue do for users? Well as some of your know unit dies **
//** when it's health drops below .405, still if you increase it's health afterwards **
//** it can cause issues with group filters and generally count the unit as alive. **
//** **
//** This system puts 2 hooks on 2 blizzard natives: **
//** native SetUnitState takes unit whichUnit, unitstate whichUnitState, real newVal returns nothing **
//** native SetWidgetLife takes widget whichWidget, real newLife returns nothing **
//** **
//** Whenever the natives are used the hooks fire off and check the widget/unit's life values **
//** Depending on their life value and the new value, it decides whether to fire the prevention or not. **
//** Prevention is fired if a widget/unit's life is less or equal to .405 and the new life value **
//** we wish to set is larger than 0.00. **
//** In case they both are true the hook will start a timer which expires in 0.000001 seconds and **
//** sets the unit/widget's life to 0.00 preventing it from having a larger value of health than **
//** 0.00 for more than 0.000001 seconds. **
//** **
//** To use this library you must use TimerUtils and simply copy this to your map. **
