Yeah, this is a bit of a bear.  launchd has a serious conceptual gap when it comes to the install, upgrade, and uninstall process.  We're tracking this as <rdar://problem/5476420>.

By far the best solution from a technical perspective is to force a restart of the system.  Obviously this is less than ideal from a UE perspective.

As to workarounds, I haven't ever investigated this properly, but I think the easiest would be for your master process to just quit and have launchd relaunch it, at which point it will profit the environment variable you specified via SecureSocketWithKey.
