Probably I can separate this change to another patch. It is not related to the
socket sharing. It is the fix of an old bug.
Host::LaunchProcess() requires to SetMonitorProcessCallback. This callback is
called from the child process monitor thread. We cannot control this thread.
lldb-server may crash if there is a logging around this callback because
TestLogHandler is not thread safe.
I've kept this code here for now because I faced this issue only debugging this
patch with 100 simultaneous child processes. It is hard to reproduce it other
way. Note also [this
comment](https://github.com/llvm/llvm-project/pull/101283#issuecomment-2259628620).
