Barring any bugs which manage to keep threads alive too long, it's going to be 
OS dependent. core.thread (which std.concurrency.spawn uses) uses pthreads on 
Linux. However, there _are_ currently some bugs with regards to spawned threads 
not terminating however, at least some of which have been fixed in the git 
repository (changes are in both druntime and phobos) but haven't been released 
yet. So, I don't know how successfully you can use spawn at the moment. 
Personally, I've had major problems with it due to bugs related to threads not 
terminating. Other people have used it successfully. Some of those bugs _are_ 
finally being fixed however, and hopefully spawn will work much better in the next 
release. Regardless, the max number of threads should be system dependent.
