On Microsoft Windows when

returns, and if LispWorks fails for some reason then the call to
On other platforms when
was true, during the automatic initialization
just causes the initialization to start and returns immediately. The initialization will finish sometime later. The LispWorks function LispWorksState can be used to check whether it finished initializing.
Automatic initialization is useful when the dynamic library is something like a server that does not communicate by function calls. On Windows it also allows
to succeed or fail according to whether the LispWorks dynamic library initialized successfully or not.
