No I have tried being a sysadmin in the past trying to help developers
install a version of java that would work with a given piece of shit
java class provided by some third party that as usual (for java class
developers) couldn't botehr to specify which revision of java they
required.  Add to that my serious dislike of object oriented code, and
java has no hope of being appreciated by me.  The existence and bizarre
popularity of the garbage named eclipse hasn't helped the situation.

I certainly know how it ought to work, and what my quick google searches
say java does or should do.  It all says it should work for multithreaded
code.  As long as more than one thread is actually trying to do something
of course.  Obviously having 200 threads with only one trying to do any
work will only get you one cpu core busy.

I don't even think I want to know what it means.
