I don't know anything about the internals of microwindows or nano-X or
anything, so take this thought with a grain of salt. Wouldn't it be
better to use rwlocks? They exist in the thread.h library in solaris, but
linux uses pthreads, hence no thread.h. However read/write locks can be
emulated using multiple semaphores, correct? Do you think that'd be worth
the effort, or no? Do rwlocks exist natively on the other platforms
supported by microwindows & nano-X? Just a thought.
