It is expected that low-priority processes should be allowed
to run about 1/8 of the time of normal-priority processes.
The proportion calculated was usually considerably lower than
1/8. It seems that the main reason is the punishement in
reductions when sending to a process that alreday has many
messages in the message queue. I have verified that by running
the emulator with the +snsp to turn off the send punishment.
To avoid that punishment, let the server process run at high
priority so that it can keep its message queue short.
It seems that the proportion is now very close to 1/8. Therefore,
we can tighten the margins for the proportion.

erl_process.c: Add more assertions in process termination
Make sure that asynchronous replies are not lost
|
|
The fix avoids registering the main thread as an emulator thread
on MacOSX. This since WX steals the main thread for its own usage
on MacOSX, and use the thread as an ordinary driver thread.

|
If a link dependency is added in LDFLAGS it should be resolved
in LIBS, so we have to use LIBS and not TYPE_LIBS.

|
Before terminating a process, add assertions to make sure that
all queues for system tasks have been emptied.
|
|
If an synchronous GC was requested by calling:
erlang:garbage_collect(Pid, [{async,Ref}])
the reply message could in certain circumstances be
lost.
The problem is in cleanup_sys_tasks() in erl_process.c.
If there were at least one dirty task, only the first
dirty task would be cleaned up. All other systems tasks
would not be cleaned up (that is, no replies would be
sent to other processes waiting for the tasks to finish).

Inroduce syntactic sugar so that we can write:
get_list xy xy xy
instead of:
get_list x x x
get_list x x y
get_list x y x
get_list x y y
get_list y x x
get_list y x y
get_list y y x
get_list y y y
|
|
In Perl 5, '&' on direct subroutine calls are optional.
|
|
Instructions that take a 'd' argument needs a -gen_dest flag in their
macros. For example:
%macro:put_list PutList -pack -gen_dest
put_list s s d
-gen_dest was needed when x(0) was stored in a register, since it is
not possible to take the address of a register. Now that x(0) is stored
in memory and we can take the address, we can eliminate gen_dest.
