I don't think a 40 KB process which does a wait4 and select every second gives much overhead, even if you count the contextswitch time. >From the perspective of security it is also not recommended. You got me thinking about it, and I came up with the following: Given the fact that the number of bugs in a program is directly proportional to the number of lines of code written, if you take this one step further you have to conclude that the number of security holes is also proportional to the number of processes which you are running or allowed to run. In other words I agree that it is good practice not to run processes which are completely useless. regards, Z.
