 Some 2.7 users are getting these messages:

  Warning: curl_exec() has been disabled for security reasons in
 /home/nicetec/public_html/wp-includes/http.php on line 1022
  Warning: curl_exec() has been disabled for security reasons in
 /home/nicetec/public_html/wp-includes/http.php on line 1027
  Warning: Cannot modify header information - headers already sent by

 Apparently, when a paranoid host decides to disable curl, even attempting
 to use it can cause a warning.

 However, the real problem is that the only check for curl capability is
 "function_exists('curl_init')". While function_exists will return false
 for disabled functions, it's not checking all of them. Although why a host
 would disable curl_exec and not curl_init is beyond me, I admit.
