[Mike Miller]

Follow-up Comment #23, bug #53635 (project octave):

Yes, that is what's going on.


## run sleep at the bash command prompt
$ pgrep sleep
19590
$ grep Sig /proc/19590/status
SigQ:   3/63696
SigPnd: 0000000000000000
SigBlk: 0000000000000000
SigIgn: 0000000000000000
SigCgt: 0000000000000000

## run sleep at the octave command prompt
$ pgrep sleep
19855
$ grep Sig /proc/19855/status
SigQ:   3/63696
SigPnd: 0000000000000000
SigBlk: 0000000003817007
SigIgn: 0000000000000000
SigCgt: 0000000000000000


The SigBlk field shows that the following signal numbers are being blocked by
the sleep process. Left as an exercise for the reader to turn the numbers into
signal names.
