REPORTING BUGS
==============
Please report any bugs encountered to
Michael.Weber@cwi.nl
Please include enough information in a bug report that someone reading
it can reproduce the problem.
KNOWN ISSUES
============
[The gaps in the number sequence belong to old bug descriptions which
have gone away.]
#1:
The VM is relatively slow on Intel Xeon CPUs (compared to AMD64).
Probable reasons:
* Cache effects; Xeon has only 512kB cache
* Pipeline stalls; Xeon has a very deep pipeline, such that
mispredicted branches are very expensive. The inner loop of the
VM does a lot of unpredictable branching...
#2: 2006-02-22
Processes do not die in stack order. No idea why this is needed at
all.
Also, if within the last step(sic!) a process-local variable is set
and then the process dies, the never claim might not see it. This
is a more serious issue. Ways around it: put "l: goto l;" at the
end of such a process.
http://spinroot.com/spin/Man/_pid.html:
"Process instantiation numbers begin at zero for the first process
created and count up for every new process added.
[...]
When a process terminates, it can only die and make its _pid number
available for the creation of another process, if and when it has
the highest _pid number in the system. This means that processes can
only die in the reverse order of their creation (in stack order)."
