10-at-a-time example skips result of the last url in single MAX_PARALLEL mode

[kuznetsov-m]

I did this

Take 10-at-a-time.c example and change next:

• MAX_PARALLEL new value is 1
• urls - left 3 items

then build and run.

I expected the following

R: 0 - No error <https://www.microsoft.com>
R: 0 - No error <https://opensource.org>
R: 0 - No error <https://www.google.com>

I received the following

R: 0 - No error <https://www.microsoft.com>
R: 0 - No error <https://opensource.org>

result of last url has been skipped.
