Possibly - I only looked into this when I was first getting started
with LLDB and enabled a large set of log channels to try to understand
how everything worked. I distinctly recall that log entries were
completely missing though, not just "interweaved" as the help for -t
suggests.

Ah, this seems a bit bizarre:

    if (log_options == 0)
        log_options = LLDB_LOG_OPTION_PREPEND_THREAD_NAME |
LLDB_LOG_OPTION_THREADSAFE;

so by default we get the thread name and threadsafe logging, but if
any options are set then they are not automatically set.

Oh, but I don't see anywhere LLDB_LOG_OPTION_THREADSAFE is checked.
