Not at the moment, but we'll see if we can reproduce it reliably. I
think our code is using ExecRunner at the moment, but we'll convert
the troublesome application to ProcessTools (which seems to make more
efficient use of the CPU than ExecRunner). We are using jdk 1.4.2, so
it doesn't seem to be version related.

One minor thing, should ProcessTools.java:518 be calling close() on
the writer? I work by the general rule that the code responsible for
opening a stream should also be responsible for closing it.

Cheers,
Len.
