+ <tag>Optimization for <c>receive</c> with unique references</tag>
+ <item>
+ <p>
+ The BEAM compiler can do an optimization when a receive
+ statement is only waiting for messages containing a reference
+ created before the receive. All messages that existed in the
+ queue when the reference was created will be bypassed, as they
+ cannot possibly contain the reference. HiPE currently has an
+ optimization similar this, but it is not guaranteed to
+ bypass all messages. In the worst case scenario it, cannot
+ bypass any messages at all.
+ </p>
+ <p>
+ An example of this is when <c>gen_server:call()</c> waits for
+ the reply message.

+ <tag>Not yielding in <c>receive</c> statements</tag>
+ <item>
+ <p>HiPE will not yield in <c>receive</c> statements where
+ appropriate. If a process have lots of signals in its signal
+ queue and execute a HiPE compiled <c>receive</c> statement,
+ the scheduler thread performing the execution may be stuck
+ in the <c>receive</c> statement for a very long time. This
+ can in turn cause various severe issues such as for example
+ prevent the runtime system from being able to release
+ memory.
