    66## Features
    77
    8 *  ASDF 3.0.1.49 shipped with the implementation
    9 
    10 *  per function call stack and memory exception handler in CL:COMPILE
    11 
    12     [???]
    13 
    148*  Make LispStackFrame?.UNAVAILABLE_ARG a singleton object,
     9   and lazily create the little used portions of the Lisp stack.
     10
     11    Aggressively cache and control the use of memory by the underlying
     12    Lisp stack frame representation by introducing the private
     13    LispThread.StackFrame and LispThread.StackSegments classes.

     15    Contributed by Dmitry Nadezhin.
     16
     17    LispStackFrame? object are allocated on every
     18    LispThread.execute(...) .  However, they are seldom [accessed]
     19    ([... verify via] inspect[tion of the] stack trace). This patch
     20    delays allocation of LispStackFrame? objects until they are
     21    requested.  Raw information about stack frames is stored in
     22    stack. Stack is an Object[] array (more precisely a list of [...]4
     23    [Mib] Object[] arrays).

     25    ME: We are going to need a way to try to less agressively grab 4Mib
     26    chunks in low memory situations.

    1628    Memory profiling of ABCL shows that the classes with largest
