Hi Brian,
I will attempt to answer some of your questions. Dr. Rupp will probably correct
any error I make in my answers.
I'm confused about when to worry about this. Does it matter for
synchronized methods?
Yes, as the system/library call you are doing might also be done by *another*
method on *another* thread.
Does it matter for all native code?
Of course.
Does ANSI
define what is reentrant?
Posix does, which is what most of Classpath's native code relies on.
Etienne
