FWIW, on Linux (some Debian oldstable with stains of stable & testing, and a 3.2.0-3, 64 bit), I'm getting 229376, wich is the expected value (it corresponds exactly with the value in /proc/sys/net/core/wmem_default). Guile 2.0.11 here, too. So perhaps it's something specific to the OSX port? regards - -- tomás -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iEYEARECAAYFAlZEYAsACgkQBcgs9XrR2kbtlwCfaCRlWG4D0rBCGZwf7XPywZez GJ0An3/9pkzRY2vmiSlLcqFQxBp6aJXc =YBbm -----END PGP SIGNATURE-----
