-* malloc() needs to block until memory is available?
+* Get rid of names for synch primitives? They increase the size of
+ each one by 16 bytes and are probably not that useful.
+ Alternatively make the names pointers?
-* Should we use a task gate for hardware interrupts? Then we could
- dedicate a stack to interrupt handling and not worry about interrupt
- usage of kernel stacks.
+* Write, test user programs.
+ - addrspace_load() should return thread's esp.
+ - thread_execute() shouldn't panic on failure (!).
+
+* Figure out PD/PT management API.
+ - We should document what's in mmu.h.
+ - pagedir.[ch] is undocumented.
+
+* Write, test VM.
+
+* Implement `jitter'.
+
+* Test list, hash ADTs.
+
+* Compile and install gdb, dbg versions.
+ - Test gdb version.
+
+* References/bibliography.
+ - Userprog refers to [SysV-i386].
+
+* Write "tour".
+
+----------------------------------------------------------------------
+
+* Cygwin support:
+ - PE linker scripts? Doesn't seem to support ELF ones.
+ - .S files need _ prefixes on symbols.
* Filesystem dumps should include filehdrs?
+
+* Cross-compile notes:
