Summary: 0.4.0 httpsrc: while(1) { malloc(); };

Initial Comment:
  
0.4.0 httpsrc seems to eat a lot of memory. When doing this to  
test my installation ...  
  
gst-launch httpsrc location=http://kronk/dukes.mp3 ! mad !  
osssink  
  
... no sound plays, because the URL is incorrect and that file  
doesn't exist. So, gst-launch going into a loop doing the following, 
according to strace.  
  
read(3, "", 4096)                       = 0  
brk(0x91cf000)                          = 0x91cf000  
read(3, "", 4096)                       = 0  
brk(0x91d0000)                          = 0x91d0000  
read(3, "", 4096)                       = 0  
brk(0x91d1000)                          = 0x91d1000  
  
It also grows quite large in size. it consumes a few MB/sec. If I  
have the URL right, it seems to work just fine. I would expect 
httpsrc to do something other than malloc() in a loop if the URL 
isn't valid. gnomevfssrc, for instance, simply aborts:  
   
  RUNNING pipeline  
  ERROR: gnomevfssrc0: opening vfs  
        file"http://kronk.house/dukes.mp3" (File not found)  
  pipeline doesn't want to play  
  
 
Even with the URL right, gst-launch gets selected for 
termination by the OOM killer, after it reaches some very large 
size. The entire test track played, and then gst-launch got 
greedy. 
 
While playing, gst-launch consumes 2460 KB -- no more, no less. 
When the track ends, it then rapidly bloats to multi-hundreds of 
megabytes. It was 181MB when I killed it a few seconds after the 
track ended. The OOM killer probably won't kick in on my PC 
(256MB phys, 512MB swap) until gst-launch reaches around 
500MB (I currently have 150MB free, 323MB swap free).
