Greetings,

I am not entirely sure as to what exactly a thread is, but seeing as anything I've ever programmed is light weight, I've never needed to worry before. And to be honest, such is still the case. This question is merely to satisfy my personal curiosity on the topic, and I can't seem to find a satisfactory answer through google.

Up until now, I just figured that something that wasn't thread safe would just crash if one attempted to access it from more than 1 thread. (Or it'd just give you some unexpected results) Recently, however, I read something that seemed to indicate that trying to thread a non thread safe class/method could lead to slightly worse problems than a crash. (The article in question mentioned 'damage your computer')

So, when something is 'not thread safe', what exactly does it mean? In addition, if one tries to thread a non thread safe class, what can the expected results be?

Thanks!
-Kevin
