* Sets the developer mode. When in user mode (the default),
* loading two classes with the same name will cause the program to abort. In
* developer mode, the new class will replace the old one. If the ivar layouts
* are the same, the new class will be treated as a category. If they are
* different, then it will replace the old one in the class table, meaning that
* message sends to the class will go to the new version, but existing
* instances will not acquire the new methods.
*
* The runtime currently only supports two modes, although more may be added in
* the future. The behaviour of the existing modes will be maintained if this
* is the case.
