After this error message:

Fatal error: EBADF: bad file descriptor, close

the current task stops instantly even of there are other things ot do for that task, without other details on issue and grunt quits. The time elapsed report is printed (so it is not an abrupt exit).

Task prints its progress with progress bar from progress with render throttling applied.

The code of task (files upload loop with progress) works fine if called outside grunt by a standard node script with same files list supplied.

node 6.16.0 npm 6.1.0 tried latest grunt and grunt 0.4.0 with grunt-cli.
