-  * The function is used only in the application 'systrace'.
-    It is rather difficult to imagine a situation, in which

-    and all system calls for support of this function are a little
-    decelerated (though not strongly)...
-  * So there is a proposition to delete from the kernel
-    support of this function, together with application 'systrace'.
-  * The information on system calls saves in the system
-    ring buffer with 0x10 entries.
-    This function simply copies the given size of data
-    from this buffer to the given address.
-  * One can determine, which entry in the buffer corresponds to
-    last system call, by value of eax, namely, it is the entry
-    (eax and 0xF) (at offset (eax and 0xF)*0x40).
-  * In the current implementation there can be the seldom
-    meeting problems of unsynchronization, when the information
-    on some calls becomes outdated.
-  * Under the system buffer one page, 4Kb, is allocated.
-    Size of an entry = 64 bytes. Why only 16 entries are used,
-    is not clearly.
-  * The value of esp at the moment of system call cannot
-    be determined by this function.
-  * The current implementation does not check edx for correctness.
