Issue analysis: My main issue was that the main() does not
waited for the new thread (I used spawn() before I opened this

Since each thread can run at different times having
thread_joinAll() would be best at the end of a loop or before
writing the output.
An alternate to writing a custom appender is simply to make the
assignment atomic. Haven't tried this but if you did 'shared
string[] lines;' then you could build the string and then append
the string to the lines. You could also avoid adding newlines
since they would be appended afterwards by a helper function.
void writeLintes(File output) {
foreach(ln; lines) {
output.writeln(ln);
}
}
I actually wonder how much of it would have to be shared at that
point, since strings are immutable then the returning/assigning
strings are safe once set; The only thing that needs to be shared
is the array that grows as the chances of reallocation.
I'll experiment with this and get back with you. Multi-threading
isn't my strong suit either.
