CogVM binaries as per VMMaker.oscog-eem.317/r2761
Fix bug in transferTo:(from:) when doing a code compaction when ensuring there is a machine code method when switching to a process whose context has a machine code pc.
Limit the ammount of space the Cogit will stack allocate when compiling. This limits the maximum number of bytecodes in a method that the Cogit will compile. Currently set at 1.5Mb of stack space from empirical tests of alloca on Mac OS X 10.6, linux 2.6 & Windows XP.
Fix become for cog methods that are not paired with their bytecoded methods (e.g. Newspeak accessors).
Linux:
There are two variants of the Linux VMs; those ending in "ht" have a heartbeat thread, while those that don't, use an interval timer for the heartbeat (the Windows and Mac VMs have a threaded heartbeat). The threaded heartbeat is better (for example, signals from the interval timer interfere with system calls, etc), but to use it one must have a kernel later than 2.6.12 and configure linux to allow the VM to use multiple thread priorities. To do so, create a file called VM.conf where VM is the name of the vm executable ("squeak" for the Squeak vm, "nsvm" for the Newspeak vm) in /etc/security/limits.d/ with contents: * hard rtprio 2 * soft rtprio 2
e.g. sudo cat >/etc/security/limits.d/squeak.conf <<END * hard rtprio 2 * soft rtprio 2 sudo cp /etc/security/limits.d/squeak.conf /etc/security/limits.d/nsvm.conf END Then log out and log back in for the limits to take effect. -- best, Eliot

CI duly updated. I _haven't_ added a VM.conf for build.squeak.org.

I updated the 4.4 all-in-one and put it here:
https://dl.dropboxusercontent.com/u/4460862/Squeak-4.4-All-In-One.zip
On linux I'm not using the ht vm.
If you attempt to use the HT vm without making the kernel modifications does it behave like the non-HT vm or just crash?
Thanks

It exits with a cryptic error message:
$ coglinuxht/squeak myimage.image pthread_setschedparam failed; consider using ITIMER_HEARTBEAT: Operation not permitted
