Yup, the problem is with the address quote.yahoo.com, gethostbyname()
returns a DNS timeout. Doing an nslookup on this address returns:
Non-authoritative answer:

Aliases: quote.yahoo.com
If instead I use finance.yahoo.com then there are no problems. Seems
like the PalmOS TCP/IP stack has problems with aliased DNS names.
Hope Palm takes a look at this.
