Title: THREAD COMMON SIGNAL HANDLING
Description: Signal handlers are assigned on a per thread basis. Signal lists
and data structures are a part of the TCB. This is incorrect.
Signal handlers are a global property of the task group: The
main thread and all of its child threads. Signal handlers for
all threads should be attach-able from the main thread, for
example.
Status: Open
Priority: Medium. This is a pretty big violation of the signal handling
principles.
