* FIXME:
* - force interface initialization for already existing classes
- * - make things threadsafe
+ *
+ * LOCKING:
+ * lock handling issues when calling static functions are indicated by
+ * uppercase letter postfixes, all static functions have to have
+ * one of the below postfixes:
+ * - _I: [Indifferent about locking]
+ * function doesn't care about locks at all
+ * - _U: [Unlocked invocation]
+ * no read or write lock has to be held across function invocation
+ * (locks may be acquired and released during invocation though)
+ * - _L: [Locked invocation]
+ * a write lock or more than 0 read locks have to be held across
+ * function invocation
+ * - _W: [Write-locked invocation]
+ * a write lock has to be held across function invokation
+ * - _Wm: [Write-locked invocation, mutatable]
+ * like _W, but the write lock might be released and reacquired
+ * during invocation, watch your pointers
