Because arrays and associative arrays are very useful, using native  
bash costructs instead of posix gives you a decent speed boost, and  
the main source of slowdowns in the boot sequence is I/O based --  
mounting filesystems and launching programs. Serious boot speed  
optimization is a matter of optimizing I/O.
