Removing "synchronized" from the 3 methods in PropSingleton has no effect
(it still throws InterruptedIOException), so it's probably not related to
that.

Fixing the possibly leaked file descriptor in PropUtil.loadProperties()
(add "is.close();") also doesn't help.

I tried reproducing this with a smaller program (just load the properties
file from another thread), but couldn't make it fail.

My jvm is "1.4.2-p6". And, it works fine on MacOS/X.

Not much help, but FYI.
