What does threadsafe mean?

Eric Lippert has a nice blog post entitled What is this thing you call “thread safe”? about the definition of thread safety as found of Wikipedia.

3 important things extracted from the links :

“A piece of code is thread-safe if it functions correctly during simultaneous execution by multiple threads.”

“In particular, it must satisfy the need for multiple threads to access the same shared data, …”

“…and the need for a shared piece of data to be accessed by only one thread at any given time.”

Definitely worth a read!
