Once I've read an excellent book, The Art of Multiprocessor Programming [0]. All examples in the book are in Java. After reading it, when thinking about some of the solutions and algorithms presented, I quickly concluded that deploying them in C/C++ would be an order of magnitude more complex, because of 'memory reclamation'. So yes, I think the OP makes a good point.

I picked this book up from the library and it is definitely a useful book. About 2/3rds of the book is actual runnable example code.

Also agree totally on Java making concurrency way easier with GC. Russ Cox describes one of these problems here https://research.swtch.com/lockfree

Typical system memory allocation locks, so being able to ignore that aspect makes lock free algorithms simpler, often because it makes them no long lock free.
