I launch one application with NSTask, but when the the launched process has exit. I find the parent process's thread will increate.

Code:
	NSWorkspace *workSpace = [NSWorkspace sharedWorkspace];
	NSString *appPath = [workSpace absolutePathForAppBundleWithIdentifier:@"com.company.someapp"];
	NSBundle *appBundle = [NSBundle bundleWithPath:appPath];
	NSString *excuPath = [appBundle executablePath];
	NSMutableArray* args = [[[NSMutableArray alloc] init] autorelease];
	NSString* arg1 = @"some args";
	[args addObject:arg1];
	NSTask* theTask = [NSTask launchedTaskWithLaunchPath:excuPath arguments:args]; 
	[theTask waitUntilExit];

On tiger. it don't increate. if there is some bugs in my code? or it's OS issue?
Thanks
