I've implemented a User Managed Sharing Using Apex and need to know are there any limits for Apex User Managed Sharing for standard or for custom objects?

All of the notes in the docs apply:
Apex sharing reasons and Apex managed sharing recalculation are only available for custom objects.
Every time a custom object's organization-wide sharing default access level is updated, any Apex recalculation classes defined for associated custom object are also executed.
The object’s organization-wide default access level must not be set to the most permissive access level. For custom objects, this level is Public Read/Write. For more information, see Understanding Sharing.
Aside from that, all standard governor limits apply, so presumably you can't recalculate sharing on an object with more than 50,000,000 rows, nor can you create more than 10,000 sharing entries in a single pass. You'll also be subject to the 250,000 asynchronous calls per day limit (shared across all asynchronous jobs).
I don't see anything in the docs about any extra limitations.
