Description:

Progress bar for "Reindex all search indexes" stays at "0%" until the indexing is complete, in order to see progress bar for "Reindex all search indexes" does not change from "0%" after minutes of indexing, a Groovy script was created in order to create 10,000 users for testing purpose.

Steps to reproduce:

1. 1. Change https://github.com/yuhai/liferay-portal/blob/master/portal-kernel/src/com/liferay/portal/kernel/dao/orm/DefaultActionableDynamicQuery.java#L426 for "_interval = 100;"
2. In Control Panel > Server Administration > Script, run create_test_users.groovy to create 10,000 (or 1000) users
3. In Control Panel > Server Administration > Resources > Reindex all search indexes > Execute

Results of testing:

Expected results: Progress bar updates as the percentage counter increments
Observed results: Progress bar does not update and always shows "0%"
