hi guys,

is that what we talking about (see patch below)?
If anybody is concerned about performance, I would be happy to rewrite
lookup to use some sort of hashing

I also tried to use koders.com to search for exec* and EACCES.
It doesn't look like any code indexed by koders is fishing
specifically for EACCES after call to exec* to do some magic recovery.
