Remarks

Given an array of packages, checks to see if each package has been loaded, and if so, unloads it before loading it again. Does nothing if the package isn't currently loaded. @note This doesn't re-order the loads to make sure that dependencies are re-loaded first, you must handle that in your calling code (

Parameters

Parameter	Description
InPackagesToReload	Array of packages to reload.
OutReloadedPackages	Array of new package pointers. An entry will be present for every item from InPackagesToReload, however they may be null.
InNumPackagesPerBatch	The number of packages to process before running a pointer fix-up and GC. More packages per-batch will process faster, but consume more memory.
