memory leak on redeploy

Atomikos is probably causing memory leak in perm gen space in application servers (tomcat 6) because tomcat's WebappClassloader cannot be gc'ed on web application hot redeploy due to atomikos putting something into thread local.

Yourkit's "Paths from GC Roots" function run on dangling WebappClassloader shows this:

com.atomikos.timing.PooledAlarmTimer [Stack Local]
  <local variable> of java.lang.Thread [Stack Local, Thread]  "Atomikos:6" native ID: 0x11BC

tried with Java 6.0.18, Tomcat 6.0.24, Atomikos essentials 3.5.5

Does anyone run into this?
