Comment (by dd32):

 For what it's worth, I couldn't cause the script to die.

 If dl is disabled via safemode or enable_dl = Off, the function simply
 returns false. If the function is disabled via disable_functions, it
 returns null.  False or Null would trigger setting it to false.

 in the above cases, is_callable() would return true, as it could be
 called. function_exists() would return false however.  This may differ in
 a binary that it was specifically removed in though, which would cause it
 to die.

 Instead, I'll commit a version which should avoid any issues..
