jlaitine opened a new pull request, #3070:
URL: https://github.com/apache/nuttx-apps/pull/3070

   ## Summary
   
   This adds checking that the signal is delivered to a correct thread, if sent 
with pthread_kill. The check is added to signest test, as it fits there with 
minimal addition.
   
   There is currently an issue in nuttx, that if the signal is masked at the 
time of dispatch, it is added to the task groups pending queue. From there it 
is later delivered, but always to any thread in the group (whichever thread 
happens to remove the pending signal).
   
   ## Impact
   
   This adds functionality to ostest's signest testing case.
   
   ## Testing
   
   Tested that after this patch,  the signest test eventually fails (at least 
on an SMP system), for the test.
   
   Note: Integrating this will cause failures before the actual issue is 
resolved in NuttX. I will provide a suggestion for fixing it as well for the 
NuttX repo.
   
   Maintainers have to decide whether this addition is 1) wanted for ostest and 
2)  whether it should be merged before or after the issue is fixed in nuttx.
