Your expectation is wrong. xargs will - by default - not start a seperate instance of the to-be-executed process for each of the arguments it reads from stdin, but instead it gathers some and feeds them to the process at once. You can limit the number or args each sub-process will be fed with -n or --max-args. I. e. echo test1 test2|xargs -t -n 1 should do what you expect. BTW: this is not Cygwin-specific.
