/proc/*/stat
When the real-time signals were added, the data in this file
was changed to hex. The latest "fixed" procps shows garbage
for Linux 2.0, while the versions used by most distributions
show garbage for Linux 2.1. (try "ps axs")
/proc/*/status
Linux 2.0 uses "SigCgt" for caught signals. Linux 2.1
uses "SigCat" for caught signals.
Proposed changes:
1. /proc/*/stat is considered obsolete, and will return to
the original behavior.
2. /proc/*/status uses "SigCgt" like Linux 2.0. The data in
this file should be used to get real-time signal information.
(it always was and still is hex)
