I've seen a lot of folks following <exec> tasks with sleep. Doesn't the exec task wait for a return code prior to returning to the caller? I inherited A BUNCH of Ant build files that were just RIDDLED with 5 minutes of sleep here 10 minutes of sleep there... The build takes half of a day to finish when all is said and done. To me, that is rediculous. I come from a dot net/NAnt environment where my longest build took 20 minutes and I wasn't happy with that one.
