Body:
I uploaded patches that fix the immediate problem. I also checked all existing tag
libs for the pattern that causes the problem: iterating down through one's Scripts,
checking their type with instanceof. Only the XML tags do this.
Of course, it's totaly bogus to do this and it should be explicitly disallowed.
However, I'm actually am somewhat stumped by a particular behavior of the XML output
and wasn't able to replace this functionality with something better.
For 1.1/2.0/sometime soon, we should fix the underlying condition in the XML tags,
which is harder than it looks at first. I'll file a jira about it.
For now, the patch passes the unit tests.

Key: JELLY-148
Summary: Huge memory leak resulting from the use of ThreadLocal
Type: Bug
Status: Unassigned
Priority: Critical
Project: jelly
Components:
core / taglib.core

Description:
There is a huge memory leak that results from the TagScript's use of ThreadLocal.
ThreadLocal is usually used from a staic variable, while TagScript uses it from an
instance variable. Although this looks legal to me, it causes a huge memory leak.
