Not exactly.  You can't necessarily call malloc/free from multiple threads.
This is a big problem for Modula-3 programs that call out to nontrivial C code.

(Why don't we wrap malloc/free ourselves in a special library?  Linker problems
I suppose... and I also suppose the effort should rather be on getting pthreads
working again than messing around with problems with user threads...)
