I inspected several JVMs for their background threading support:

Linux Sun JVM 1.4.1 no
Linux Sun JVM 1.3.1 no
Linux Blackdown JVM 1.4.1 beta no
Linux Bea JVM 1.4 --
Linux IBM JVM 1.4 no
Solaris Sun JVM 1.4.1 no
MacOS-X Apple JVM 1.4.1-a7 yes
Windows Sun JVM 1.4.1 yes

no - behaves like simple round-robin scheduler (ignoring priorities).

A sample microbenchmark attached.
