[hobbit] Large number of TIME_WAITs

[Hubbard, Greg L]

What OS?  Some operating systems allow network connections to hang
around a bit after disconnection.  On Solaris you can set a parameter to
reduce the timeout period.  Hobbit could trigger this because each
client connects to the server, sends a data blast, and then disconnects.

	I noticed something strange on my Hobbit server, though I'm not
sure if it's a problem or not.  There are about 140 TIME_WAITs from the
local IP of the Hobbit server, and about 30 TIME_WAITs from localhost,
all using port 1984.  They look something like this:
	
	0      0 1.2.3.4:42389         1.2.3.4:1984          TIME_WAIT
	0      0 1.2.3.4:42394         1.2.3.4:1984          TIME_WAIT
	0      0 1.2.3.4:42399         1.2.3.4:1984          TIME_WAIT
	0      0 1.2.3.4:42396         1.2.3.4:1984          TIME_WAIT
	0      0 1.2.3.4:42397         1.2.3.4:1984          TIME_WAIT
	
	0      0 127.0.0.1:42310             127.0.0.1:1984
TIME_WAIT
	0      0 127.0.0.1:42309             127.0.0.1:1984
TIME_WAIT
	0      0 127.0.0.1:42315             127.0.0.1:1984
TIME_WAIT
	0      0 127.0.0.1:42322             127.0.0.1:1984
TIME_WAIT
	0      0 127.0.0.1:42320             127.0.0.1:1984
TIME_WAIT
	
	There are also a few on various other ports:
	0      0 127.0.0.1:42246             127.0.0.1:29021
TIME_WAIT
	0      0 127.0.0.1:42301             127.0.0.1:29023
TIME_WAIT
	0      0 127.0.0.1:42362             127.0.0.1:29017
TIME_WAIT
	0      0 127.0.0.1:29030             127.0.0.1:42380
TIME_WAIT
	0      0 127.0.0.1:42348             127.0.0.1:29019
TIME_WAIT
	
	
	Any idea why there should be so many of them, particularly on
the localhost address?  And any idea if this looks abnormal or not?
