Description 
in expect 5.38.0 on solaris 9, run the following:
script: 

for { set i 1 } { 1 } { incr i } {
    spawn echo foobarbaz
    expect {
	"foobarbaz" {
	    puts "ok"
	    expect eof
	    wait
	}
	eof {
	    puts "$i passes"
	    wait
	    exit 1
	}
    } 
}

It also appears to fail in expect 5.26.0

It should loop forever; instead, it exits after a few iterations on multiprocessor systems running s10.
It appears to loop "forever" on s10 uniprocessors.

A user at  xxxxx  reports that it exits after "40 to 400+" iterations on a (uniprocessor) sunblade 100
