ChucK is the main inefficiency, huh huh.  As for reducing hiccups, there
are several ways, depending on the hiccups you are experiencing.

One common type of hiccup arises when a shred is added and then tries
to load a big sound file.  Since we haven't implemented chunking in  
sndbuf
yet (it's on the todo list), a sufficiently large file will cause the  
hiccups.
you can try to alleviate the problem for smaller files by using a bigger
buffer size, for example when starting the chuck listener loop:

     chuck --loop --bufsize2048

However, this is more complicated on Windows XP, since we seem to be
having audio problems when using a buffer size greater than 512 since
upgrading to the new RtAudio, which drastically improved latency on
Window XP, but for some reason isn't liking large buffer sizes.

Also in the works, though the implementation may not happen for a
few more releases.

Theoretically we have global variables and functions.  You can declare
a public class with static members and those should be accessible by
all subsequent code.  For example:

public class The
{
     static int number;

     // a bug forces one to declare static objects as references
     static Event @ event;
}

// instantiate the event outside (thanks to bug)
new Event @=> The.event;

Having first compiled the file containing The, subsequent code should
be able to access The.number and The.event.
