1. It is possible, in rare, very specific circumstances to cause a memory 
fault when running an application that uses SCS threads

Allow the use of a new PTHREAD_CONFIG parameter
to determine if SIG_PIPE gets converted to an exception,
The only instance in which SIG_PIPE does not get converted
to an exception is when the PTHREAD_CONFIG parameter 
feature=pipe-ignore" AND SIG_PIPE masking is set to SIG_IGN

2. It is possible that,  in certain sitations, the /proc file system will  
remain open after exiting the application.
