Cloned to track potential release into 3.6.x stream.
Note: need to check actual code changes between master and bug 323322. Might not need to change anything here.

While investigating what is going wrong in shared installs, I came across the following issue that is probably the root cause of the problem for shared installs. 

The resolution is not stable when being re-run. To be more precise, when I try to install an IU in the context of some repositories, then cause a re-resolution of the resulting profile, IUs are being dropped.
Even though this looks not important, because internally p2 re-resolves the current profile to generate the attachment of IUs, this ends up being a key issue.

To show the problem, I have released a test case called EPPPackageInstallStability in the 3.6 branch. At this point I have not found a way to solve this problem.
