This is strange. 

I have an unpatched Jed Version: 0.99.16 S-Lang Version: 1.4.9 here on a
Debian-Linux sarge with bash and I do not get the b-s.
The echoed string is only 4090 characters long, the other characters
get lost.

What makes the problem worse is, that sending the string in pieces
doesnot help, if there is not enough time for the process to process it.
(And what is enough depends strongly on the process and a set of unknowns.)

Sorry, the posted test was a quick hack from my version which depended on
some of my extension modes...
