444359 - Camino hangs on launch sometimes (in RNG_SystemInfoForRNG)

Attachment: Sample

About once or twice a month, Camino hangs when I launch it just after booting my machine in the morning.

It's hanging in RNG_SystemInfoForRNG trying to gather entropy as SSL is being intialized for a site icon request. I think SystemInfoForRNG() is trying to call netstat:

and maybe netstat doesn't like being woken up so early in the morning.

Er, Camino 1.6.1 (1.8.1.14 2008051211), Mac OS X 10.5.4, 2 x 3 GHz Dual-Core Intel Xeon Mac Pro, 6Gb RAM etc.

Wouldn't that make this Core or NSS, then?

Yeah

If Mac OS X has /dev/urandom, perhaps we should add
defined(DARWIN) to this line in unix_rand.c:
http://mxr.mozilla.org/security/source/security/nss/lib/freebl/arcfour.c#408

981 #if defined(BSDI) || defined(LINUX)
982     if (bytes)
983         return;
984 #endif

Is there any problem invoking "netstat -ni" on Mac
OS X?

Sorry, the MXR link should have been
http://mxr.mozilla.org/security/source/security/nss/lib/freebl/unix_rand.c#927

Wrong again.  Here is the correct link:
