Clarification on backgrounding and detach

[c***@CSIC.UMD.EDU]

Since everything is
not NOT detached,

So now the only
difference between a
background and
foreground process
is that
the parent will
always call Wait()
on foreground
process and not on
background ?


So we just need to
check in syswait
whether the process
is background or not
and either wait or
return error code
accordingly ?

I do not see why you need to modify Sys_Wait. We already have a
nonblocking WaitNoPID for background processes. Sys_Wait remains as such.
