I tried your fixes through `cvs update'. Unfortunately, the
fixes make nothing about the problem, too. I replaced the strace
log with one which may be more helpful for your debugging.

In the strace log, I executed the bash command without any
environment variables nor /etc/{termcap,passwd,group}, and
simply typed `a\n' three times. The bash didn't consume a cpu
until two times. After I typed three times, it began to do so.

Anyway, my NT box has two CPU. Multi-processor systems hit
problems about race conditions more often than uni-processor
ones.
