Solved the problem with bjam going into an active wait state, hogging up processor resources, when waiting for one of its child processes to terminate while not all of its available child process slots are being used. To see this bug in action, try compiling a simple C++ program on a 2 processor PC with the -j 2 command-line option and watching how much processor resources bjam uses while linking. Was caused by treating unused process slots as used in the try_wait() function, causing the WaitForMultipleObjects() Windows API call to exit instantly with an error which was then getting incorrectly interpreted as a timeout, starting the whole cycle anew.
Solved a race condition between bjam's output reading/child process termination detection and the child process's output generation/termination which could have caused bjam not to collect the terminated process's final output.
Extracted all GetExitCodeProcess() API calls into one location so it no longer gets called in three separate places.
Minor comment changes in code touched by previous fixes.
