This variable does not contain "sigs" (plural).
It contains either 0 or (one) signal number of a pending signal.
For someone unfamiliar with this code, "pendingsigs" name is confusing -
it hints at being an array or bit mask of pending singnals.

"pending_sig" is the name in use in another ash derivative, busybox's ash.
I would like to ask you to use exactly this name (not, say, "pendingsig"),
if possible, so that our code does not needlessly diverge further.
