Hi folks,

is there any technical reason for not allowing rmdir("."), or is it just 
to protect the user from something {s,}he might eventually not want to 
do? I'm not interested in a flame war, I just want to know the reasons 
for it. (I'm still too young to know everything about Unix-like systems. ;))

http://www.opengroup.org/onlinepubs/009695399/functions/rmdir.html says 
removing the current working directory is allowed.

By the way, the error code is wrong. It should not be EINVAL, but EBUSY.
