Is this intended to fix the "more than 255 tasks segfault?"
It seems to fix it when there are N tasks each just blocking
indefinitely. (This code would reliably segfault under 1.6.0 for N>=
255.)
I have code which creates N tasks which sort M random itmes P times.
As long as I'm careful not to set M so high that I blow out the C
stack of the tasks, I can use almost any combination of M, N and P as
long as N <= 255. So sorting 10,000 items 50 times in 255 concurrent
tasks is fine, if somewhat slow :-)
With N >= 256, the code always segfaults, even with, say, 10 items
sorted 10 times, or even 1 items sorted 1 time.
FWIW I set LUATASK_PTHREAD_STACK_SIZE to 2097152 (2m) in my makefile.
Of course if this version isn't intended to address the "255" issue
then ignore this email -- though note that the "just blocking" case
above always segfaulted at 256 with 1.6.0 yet doesn't now. Though this
could be down to the fact that the binary is rebuilt and thus
differently laid out...
