fix math class
wrap shm_open/shm_unlink somewhere
move sleep methods into another class

file class:
	need static versions of create methods
	move create*Link/resolveSymbolicLink into link class

can getData methods in dict/linkedlist classes be const?
a bunch of static methods can probably be inlined

freebsd IPV6_V6ONLY??? socket option
sysctl on netbsd?

should be able to associate a zlib handle with a file descriptor and read/write
	compressed data, just like ssl
	
probably can combine memorypool and variablebuffer classes
memorypool actually just works the same way that malloc tends to work, I'm not
	sure using it nets anything

xml:
	dtd class needs to store +/* child element modifiers
	should be able to validate an xml document against the dtd
	bug in xml comment parsing, ! gets prepended to value
	xmldom should support xpath
	xmldomnode should probably use list class
	test invalid xml
	handle CDATA/internal subsets better
	is xmldom really DOM compliant?
	xml classes need to support entities defined in the DOCTYPE declaration

implement these classes:
	directorylisting
	link
	pipe
	serialport
	tty
	pseudotty
	shellcommand
	process
	system
	loginrecord
	messagequeue
	thread
	sslcontext
	table (dynamic 2d array)
	generic parser/lexer classes, use them for xmlsax

tests for:
	intervaltimer
	dynamiclib
	math
	rawbuffer
	memorymap
	mutex
	serialportprofile

need to use internally:
	rawbuffer class intstead of mem*()
	memorymap class intstead of mmap*()
	mutex class instead of pthread_mutex_*()

get a mingw port working
