Yes.  The linux emulator emulates the clone() based threads of Linux
kernels from 2.2 through 2.4 (NPTL of 2.6 would only show up as one
thread).  In that approach each thread shows up as a separate process.
If you don't want this then switch to the native 1.4.2 JDK and you'll
only see the one process.
