#3493: Boost::Test enters endless loop when running in vserver environment
--------------------------------------------------+-------------------------

Milestone: Boost 1.41.0 | Component: test
  Version: Boost 1.40.0 | Severity: Problem
 Keywords: |
--------------------------------------------------+-------------------------
 Boost::Test tries to find out if a debugger is attached by iterating
 through the process tree until ppid 0 is reached. Some vserver kernel
 emulate the init process in a way that ppid of process 1 is 1. This lets
 the debugger search function go into an endless loop.

 Since pid 1 is unlikely to be a debugger, we can safely ignore
 pid 1 and just quit searching when we reach pid 1 instead of 0. The
 attached patch implements this.

 We observed this bug with standard Debian Lenny vserver host running
 Debian Lenny guest and Centos 5 guest.
