Immortal process - ps stat 'T'?

[Neil Bird <neil@xxxxxxxxxx>]

  Just had a process we were debugging through ddd/gdb.  It/all it's 
threads were status 'T' ("trace"?) [except for one zombie], and it just 
wouldn't go away.  It had a port open that we then could not re-use.

  I understand that 'T' would probably have something to do with gdb 
being attached, but that had long since gone away.  Any thoughts as to 
how I should have killed it?  Had to reboot in the end.
