Subject: Apache does a full load, unload, load cycle for each DSO module.
X-Git-Tag: php-4.3.0dev-ZendEngine2-Preview1~459
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=b2f9b6fb1645317dec3788b059211ae1d50fe96f;p=php

Apache does a full load, unload, load cycle for each DSO module.
This patch makes sure that any startup actions that are performed
for PHP don't happen until the second load (the second call to
the post_config hook), and it also prevents subsequent calls
to the initialization routines.
