support of PHP 7.3 about fastest

[DonCallisto]

PHP7.3 Is still RC version so we should not hurry on it.
Let's wait for a stable release and then we can try all necesarry to reproduce and understand the issue, eventually.
I close this for the moment.

@DonCallisto PHP7.3 is already RC! RC2! => this problem is unknown for PHP developers.
I can't make for them real small sample of the problem for bug report. Possibly you, as developer of this program, can try to help them to find the problem.

[DonCallisto]

I know is RC. I'm just saying that we should not hurry until an "official" PHP7.3 version.
BTW I can try to add PHP7.3 to travis matrix and see if tests fails. If they won't fail, I'll need you to replicate this issue in a fresh repo in order to understand what's going on.

Possible problem in Symfony/Process: symfony/symfony#28655

Nice catch, so it seems not to be a fastest issue. I'll subscribe to that topic. Thanks.
