[Moved to DR at the November, 2016 meeting.]
According to 6.9.2 [intro.multithread] paragraph 23,
Two actions are potentially concurrent if
they are performed by different threads, or
they are unsequenced, and at least one is performed by a signal handler.
This definition should exclude the case when both actions are performed by a signal handler.
Notes from the October, 2015 meeting:
SG1 agrees that the existing wording should be amended to say something like “and they are not both performed by the same signal handler invocation.”
Proposed resolution (November, 2015):
Change 6.9.2 [intro.multithread] paragraph 23 as follows:
Two actions are potentially concurrent if
they are performed by different threads, or
they are unsequenced,
andat least one is performed by a signal handler, and they are not both performed by the same signal handler invocation.
