Bertrand Delacretaz commented on SLING-6274:
--------------------------------------------
I can reproduce this on the trunk launchpad/builder by creating two nodes:
* {{/system/sling/installer/jcr/pauseInstallation/foo}} which activates the
installer pause mode
* {{libs/x/install}} or any other new installable folder which causes the pause
to become effective.
When this happens, the installer doesn't wait between calls to runOneCycle, as
it usually does, and calls it in a tight loop.
