# Unfortunately, due to https://go.dev/issue/22315, cp + exec is racy.
|
|
# Since we run multiple test scripts in parallel as goroutines,
|
|
# if one thread performs a cp while another is forking, the other may keep the
|
|
# file open slightly longer than we think, causing the fork to fail due to the
|
|
# file still being open for writing.
|
|
# Until the root problem is fixed, add a sleep to try to make that narrow window
|
|
# of time less likely to cause problems.

# TODO(mvdan): remove the sleeps once cp + exec isn't racy anymore.
