note 101838 added to function.pfsockopen

I am trying to figure out how the locking / synchronization works on pfsockopen, if there is even any? Example is: $fp = pfsockopen("myhost.com", 80, $errno, $errstr); fwrite($fp, "MyRequest1"); $data = fread($fp, 8192); /* Server should now spend specific answer */ What if your server is very heavily loaded, and another script calls pfsockopen() and its own fwrite() on the same host/port between the fwrite and the fread of the currently executing script? Would this then cause incorrect information in the data read (out of sync?) or does PHP have some sort of protection against this.
