@ page 297 line 9660 section exec objection {drb.6.exec.threads.2}

Problem:

Defect code :  2. Omission

The "catchall" paragraph (lines 9660 - 9662) does not account for the fact that 
some attributes once attached to the process are now attached to individual 
threads within the process:

"All other process attributes defined in this volume of IEEE Std 1003.1-2001 
shall be the same in the new and old process images. The inheritance of process 
attributes not defined by this volume of IEEE Std 1003.1-2001 is 
implementation-defined."

On general principles, this should be adapted to account for any thread 
attributes that might be omitted in more specific text.

Action:

Replace the paragraph with the following:

"All other process and thread attributes defined in this volume of IEEE Std 
1003.1-2001 shall be set in the initial thread and process in the new process 
image as visible to the thread that called the exec function in the old process 
image. The inheritance of process or thread attributes not defined by this 
volume of IEEE Std 1003.1-2001 is implementation-defined."
