Maybe really some parallel capability could be added specifically to the 
try_compile() command. 
Which calls cmMakefile::TryCompile(), which calls 
cmGlobalGenerator::TryCompile(), which ends up in cmGlobalGenerator::Build(), 
which finally calls  

if (!cmSystemTools::RunSingleCommand(command, outputPtr,
                                       &retVal, 0, verbose, timeout))

Maybe just this one call could be put into threads somehow ?
