Comment (by gdt):

 I would be really surprised if read() returned and later memory got
 modified (because of that previous system call).

 With threads, though, the usual issues about reuse of static buffers
 apply.  Presumably that's not it or it woudl have shown up elsewhere.


 I wonder about a test entropy source that sometimes takes a long time, and
 sometimes returns fewer bytes than requested, as a way to make the tests
 more harsh.   This could perhaps be done by stubbing the read with a
 routine that does the actual read, and then maybe sleeps, and maybe
 adjusts the bytes read.
