Changes between Initial Version and Version 1 of Ticket #18738, comment 9

initial	v1
8	8	* We control the way the fsockopen class works in every respect, we can catch when it doesnt work
9	9	* It'd be nice to have 2 classes support non-blocking correctly, especially the ones given priority
10		* fsockopen was originally added last as the builtin libraries were supposed to do it better than we would in PHP.. ultimately, ~~tests seem to say curl~~
	10	* fsockopen was originally added last as the builtin libraries were supposed to do it better than we would in PHP.. ultimately, bug reports have always pointed to the opposite, often with server configs we just can't work around ( safe mode issues and curl not being able to do DNS lookups, off the top of my head)
11	11	* Streams (fopen) is also great at failing to spawn cron on setups using .local dns, Often seen in mac's, fopen() fails to open a loopback connection, also seen in Ubuntu installs occasionally.. this is what prompted me to come find this ticket again.
