Are there obstacles to doing that, like requirements for non-thread-safe
api's?
How about performance, if you have hundreds of such threads? Has anyone
experience with that? Would it necessarily be less efficient that
hundreds of java threads? Or more efficient?
pthreads are POSIX threads, right? What dodes that have to do with
running the JVM?
Modern JVMs can use platform specific (a.k.a native) threads, or green
threads of necessary. "What is the efficiency for a number of
threads?" is a trick question. It depends on a lot of factors,
including number of CPU cores, platform, what the threads are doing,
amount of available memory, etc...
If you really want to know more about concurrent programming, I
recommend the book Java Concurrency In Practice <http://
JavaConcurrencyInPractice.com/> It tells you all you need to know
about thread-safety and the thread safety of common Java API's, as
well as creating your own efficient multi-threaded programs.
Hope this helps,
