誰知道cronsched的用處？

unixboy1106

SCO中默認(rèn)的cron文件中通常會(huì)有如下兩行：
0 0 * * 1-5 scosh cronsched -r
0 0 * * 1   scosh cronsched -wr

GOOGLE了一下，大概的解釋為：
The cronsched entry in cron is used by the system to generate
the calendar files requested by users option settings.
The "r" means: add a random time variation to the time setting
so that every machine does not try to access the calendar server
at the same time.
The "w" means weekly instead of daily.

我想知道這個(gè)作業(yè)的執(zhí)行機(jī)制如何，好像一旦調(diào)用，ipc隊(duì)列會(huì)堵塞，影響上面跑的應(yīng)用，我想注釋這兩行，請(qǐng)問有什么隱患么？

謝謝各位達(dá)人！
