The `Mutex` is locked with the `MutexLock` before spawning the thread, so that the thread is prevented from completing (by being blocked on `Mutex`) before the new thread count is obtained. However, the existing bug (introduced in 22e6055) releases `Mutex` before obtaining the new thread count, which allows the thread to run to completion in the meantime.
Also, since the `(thread_count_after_create != starting_count + 1)` condition (line 328) skips the remainder of the `for`-loop body on every iteration, `thread_count_after_join` stays uninitialized.
I believe this is why [this test failed][1] on the macOS CI with this trace:
```

`TestNonHelpFlag` is only a few asserts with no logic, which is easier to read in line, and helper `TestHelpFlag` is used in a single test case.

The last regular expression specified in the test is not technically
POSIX compatible. Use `[[:alnum:]_]` instead of `\w+`; the latter is a
Perl-compatible regular expression.

The test supported a variety of BSDs, including kFreeBSD, but not FreeBSD.
Move the BSD checks to a separate function and support checking for
FreeBSD, in addition to kFreeBSD.

This commit removes `<iomanip>` from public GoogleTest header files.
As `<iomanip>` is not a common included file, its content is unlikely
to be included in translation units other than through GoogleTest
includes.
By reducing the number of include directives public headers in
GoogleTest, this may reduce the time taken to compile tests as it would
reduce the amount of work that the preprocessor and compiler front-end
need to do.
This allows types that provide an AbslStringify definition to be streamed into GoogleTest macros.
