This change fixes a race condition: The failed early pre-registration request obviously cannot return the team ID, if the other thread launching the app has not finished step 3 yet. Thus the argv/refs message would not get delivered and Launch() would not return the correct team ID. Now we wait for the pre-registration to be finished in this case, using the former _IsAppPreRegistered() mechanism, which already provided such a waiting feature for one request. It has been extended to accomodate an arbitrary number of waiting requests and renamed to _IsAppRegistered(). This fixed bug #763. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18728 a95241bf-73f2-0310-859d-f6bbb57e9c96 diff 5f8e562f Thu Jun 16 12:53:24 MDT 2005 Axel Dörfler <axeld@pinc-software.de> Added a ToDo comment. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@13185 a95241bf-73f2-0310-859d-f6bbb57e9c96 diff 5dccfc19 Thu Jul 29 00:49:17 MDT 2004 Stefano Ceccherini <stefano.ceccherini@gmail.com> Some small changes (mostly suggested by Axel).
