java/util/zip/3GBZipFiles.sh has '@ignore ignore runs for hours and eats up 7 Gigabytes of disk space'; canonically, @ignore should be followed by the id of the bug which describes the problem and will be used to eventually fix it.

the more appropriate solutions for a situation when tests have special requirements:
 - use `@requires` to check that the necessary conditions are met. in this case, this might including the creation of new at-requires property (in /test/lib/jtreg-ext/requires/VMProps.java or better a separate EnvProps class) which check how much of disk space is available;
 - using custom check login in tests and throwing jtreg.SkippedException;
 - using '/manual' jtreg option, which will exclude tests from automated runs, yet will still be possible for "manual" execution by direct jtreg invocation.

please note, that currently, both @run are excluded when jtreg is run w/ -ignore:quite (which is what run-test uses), to restore "fast" @run, the test should be split into two sub-tests -- two comment section where each one starts w/ @test tag. `@requires` solution will also require the test to be split, as `@requires` applied for the whole @test, not an individual @run.
