You're right, these are issues of D's standard library that are 
not easy for a newcomer to tackle. In case of Python's 
parallel.Pool() separate processes do the work without any 
synchronization issues. In case of D's std.parallelism it's just 
threads inside one process and they do fight for some locks, thus 
this result.
