About your script changes, I like to make it portable, and I use the
following versions:

GNU bash, version 2.05b.0(1)-release (i386-redhat-linux-gnu)

dd (coreutils) 4.5.3

What shell and coreutils are you using?

Avoiding short counts is easy but avoiding C-style expressions is primitive

- count=100K
+ count=100000

- while (( i-- )); do
+ while (( i=`expr $i - 1` )); do

In your opinion are your changes more portable across a wide range of systems?

It has a hard time to read anything else, the slower the disk, the worse.

Suppose rmap undoes the fixes introduced in -rc6.

Have you tried -rc6 plain?
