Running tests in parallel has unexpected results

[Su3h7aM]

Context

I am creating a neotest adapter to run Odin tests in neovim.
Using neotest it is possible to run individual tests, by file or by directory, when I run the tests by file I cannot use the -file flag because some tests may depend on other files, so I am using the -define:ODIN_TEST_NAMES=main.test_part01 flag, I also cannot use -define:ODIN_TEST_NAMES=main.test_part01,main.test_part02 because the tests need to run separately.
At this point I encountered a problem, because neotest runs the tests in parallel, and the odin test command does not behave as it should.

To reproduce

#!/bin/bash

odin test 2024/odin/day02 \
    -define:ODIN_TEST_LOG_LEVEL=warning \
    -define:ODIN_TEST_TRACK_MEMORY=false \
    -define:ODIN_TEST_FANCY=false \
    -define:ODIN_TEST_NAMES=main.test_part01 &

odin test 2024/odin/day02 \
    -define:ODIN_TEST_LOG_LEVEL=warning \
    -define:ODIN_TEST_TRACK_MEMORY=false \
    -define:ODIN_TEST_FANCY=false \
    -define:ODIN_TEST_NAMES=main.test_part02 &

wait

Expected Behavior

Only one of the tests must pass

Finished 1 test in 160.542µs. The test was successful.

[ERROR] --- [2024-12-24 18:57:29] [main_test.odin:34:test_part02()] Part Two: 4

Finished 1 test in 186.031µs. The test failed.
 - main.test_part02     Part Two: 4

Current Behavior

Only one of the tests runs in both cases, sometimes both pass and sometimes both fail.

Finished 1 test in 160.542µs. The test was successful.

Finished 1 test in 183.505µs. The test was successful.
