ant really slow, 100% CPU?

I've just rebuilt ant and now its really, really slow to
build. I've 
just rolled back those extra synchronized bits I'd added,
and that 
doesnt seem to be it.

-its spinning at 100%, and its memory footprint is high,
even given that 
this is a 64-bit JVM:


   PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+
 COMMAND 

24273 slo       17   0 1402m 326m 9512 S  100  5.5   2:18.35
java

it could be swapping, but heap useage is actually pretty
slow (currently 
about 50MB, according to jconsole).

-can anyone think of an obvious change in the last couple of
months that 
would slow things down?
-has anyone else noticed a change in performance?

I have not noticed any slowdown.
./build.sh on a clean system report 18 seconds to compile
everything (excluding the optional regexp, oro and netrexx
jars)

It is with tests or without?

ie. ./build.sh, or ./build.sh test
