wild socket 6 type?

Hi there, I am trying to use a variation of the mget.c
sample program to download a number of web pages
in a non-blocking manner.  I am using the HTHost_setEventTimeout
function to control the amount of time requests are allowed to
take.  Although sometimes the program executes fine, the 
program often hangs and the following type of trace is generated:

Load End.... OK: `http://lycospro.lycos.com/srchpro/?aloc=sb_srp_advwebsites&first=11&type=advwebsites&query=+%2Bml%3Awww.cs.ualb\
erta.ca&t=all'
Net After... calling 0x8048db0 (request 0x80536b8, response 0x8088788, status 200, context (nil))
Request..... Delete 0x80536b8
Request..... Deleting dangling output stream
Chunkstream. FREEING...
Response.... Delete 0x8088788
Host Event.. wild socket 6 type = Event_Read real socket is -1
Host Event.. wild socket 6 type = Event_Read real socket is -1
Host Event.. wild socket 6 type = Event_Read real socket is -1
(this last line repeats indefinately)

I am new to the library and am unsure as to what this indicates.  If anyone has any
suggestions or knows of where I can find a list detailing the meaning of various trace
messages that would be most helpful.  Thank you.
