Non-deterministic output by IPC-Grate

[drapl0n]

Non-deterministic output is caused by IPC-grate on each execution due to the following tests:

• test_pipe_large();
• test_unix_connect_accept();
• test_fork_pipe_inherit();
• test_pipe_pipeline();
• test_socketpair_fork();

Example:

~/lind-wasm$ scripts/lind_run ipc-grate.cwasm ipc_test.cwasm
=== ipc grate test ===

[test_pipe_basic]

[test_pipe_large]

~/lind-wasm$ scripts/lind_run ipc-grate.cwasm ipc_test.cwasm
=== ipc grate test ===

[test_pipe_basic]
