Indeed, but be precise - chek that it _is_ error 3, or more portably,
errno.ESRCH. POSIX probably mandates that that is a 3, but the symbol
should track the local system if it differs. Example:
import errno
...
try:
...signal...
except OSError, e:
if e.errno == errno.ESRCH:
pass # or maybe an info log message
else:
raise # something else wrong - raise exception anyway
Cheers,
