* Because we need a per-thread errno, we define a function

* pointer that we can call to return a pointer to the errno
|

* for the current thread. Then we define a macro for errno
|

* This makes it syntactically just like the "real" errno.

* Using a function pointer allows us to use a very fast
|

|
|
* function when there are no threads running and a slower
|

|
* function when there are multiple threads running.
