description:
Tests: improved proxy_unfinished.t performance.
There is no real reasons to use "for (1 .. 10000) { print ... }" loops
in the test server, yet they require a lot of CPU, leading to occasional
test failures on slow hosts. Accordingly, such constructs were changed
to prints with large buffers instead.
