You could use Python do control threads in a cross-platform way, but
you'd probably be better off using a C or C++ threading library, since
otherwise you'd expend unnecessary effort calling Python threading
primitives from C++. You might want to look at the omnithread part of
omniORB, which provides a cross-platform C++ threading interface. See

  http://omniorb.sourceforge.net/

You can see the omnithread header at

  http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/*checkout*/omniorb/omni/include/Attic/omnithread.h?rev=1.21.2.13&only_with_tag=omni4_0_develop

Not in a cross-platform way without cooperation from the threads. The
easiest thing is to have the threads you might want to pause check a
flag once in a while, and block on a condition variable if they are
asked to.

Cheers,

Duncan.
