Almost certainly.  proctitle_init() copies the environment to some newly 
allocated memory, and sets the old pointers (envp[i]) to NULL.  
Assuming the kernel uses these pointers (while libc uses its own 
environ pointer) to fill /proc, the environment file would end up 
empty.

The size seems odd, but I guess that's something to do with the way the 
kernel calculates/caches the environment size.
