The reportScoverage task spawns a separate JVM process. Would it be possible to run it within the gradle process?

For a gradle project with many sub-projects, spawning a JVM per subproject for test coverage reports ends up slowing down the build with the JVM startup time and with a cold JIT for each subproject report. Keeping the reporting task within the gradle process could shave about 1.5sec per subproject.
