Bash cpu usage after background task ends

In my experience under the cygwin-1.1.4.tar.gz
package, bash will tie up 100% of the cpu upon
completion of any background task (example: ls &).
This continues until ANY valid key is pressed in the
initiating shell's window, not just the enter key as
has been reported earlier.
Yesterday I downloaded the older cygwin-1.1.3-1.tar.gz
package and copied only the cygwin1.dll to my bin
directory. With this being the only change to my
system, background tasks now terminate normally
without forcing bash to dominate the cpu.
Here is my cygcheck -s information for reference:
