I'm using ginkgo to run the testcases in a project that has 26w lines of code, with the -p flag enabled.

Issues

1. When running testcases in parallel, more cpu cores lead to more duplicated lines. If I add the -p flag and run on a 64 cores machine, the size of cover.out file is 7.9GB. And the size of cover.out file is 130MB when -p flag removed.
2. All the coverage files are read into combined buffer, which use lots of memory. And ginkgo will be oom-killed.
