[SR-Users] Thread safety of shared variables

[Daniel-Constantin Mierla]

For what kind of operation?

Reading or setting the value are safe, but updating it with its own
value used in an expression is not.

Safe:

xlog("value is $sht(x)\n");
$sht(x) = 1;

Race:

$sht(x) = $sht(x) + 1;

Cheers,
Daniel
