There are at least 3 lists of things that effect how sudo mangles the 
environment: env_keep, env_check and env_delete. In theory,

- anything in env_keep should be kept
- anything in env_delete should be deleted
- anything in env_check is checked to make sure it's not a shell function

env_delete has a default setting to remove all LD_ variables (written as 
LD_*), so i'm trying to remove that from env_delete, and also trying to 
remove LD_PRELOAD explicitly from env_delete in case it is in there. 
then i add LD_PRELOAD to env_keep as extra assurance... except it 
doesn't work. I've tried many variations and permutations, all without 
any luck so far.
