I believe that pthreads-win32 tried something like this (using exceptions to
implement thread cancellation), and as a result they have this in pthread.h:

#pragma message("When compiling applications with MSVC++ and C++ exception
#pragma message(" Replace any 'catch( ... )' with 'PtW32CatchAll' in POSIX
#pragma message(" if you want POSIX thread cancelation and pthread_exit to

#define PtW32CatchAll \
        catch( ptw32_exception & ) { throw; } \
        catch( ... )

This means that if you want cancellation to work reliably, your thread can't
execute any code that you don't have the source for unless you can somehow
be sure that it never uses catch(...). For a general purpose library, this
is at best very kludgy.
