Most of this is is not related to using C. Details below.<br><br><br>> -- Threads work perfectly in PM3. In CM3 it's very much ???<br><br>PM3 only uses user threads, right?<br>And the only problem with user threads on CM3 currently is that it depends on pthread_atfork<br>recently and hopefully briefly, and libc/libpthread is broken on some systems and we have to workaround.<br><br><br>> -- It took five years to get TEXT working acceptably (as in, no stack<br>> overflows!) in CM3. Now seems more or less OK, but Text.Hash is<br>> still possibly an order of magnitude slower than .<br><br>Unrelated.<br>I strongly suspect the problem here is in the library design.<br>It is ok to have a readonly string type, but programmers should also have<br>access to a writable/growable string/buffer type.<br>See what C# and Java do.<br>I suspect TEXTs problems stem from trying to make TEXT be both types in one.<br>i.e. handling a lot of concatenation efficiently.<br><br><br>> -- I have no debugger that works for CM3. m3gdb is *very useful* for<br>> the old PM3.
