Could not compress the PHAR: the compression requires too many file descriptors to be opened

Bug report

Question	Answer
Box version	3.8.0
PHP version	7.2.18
Platform with version	OSX

When trying to compile Box, I got:

 [ERROR] Could not compress the PHAR: the compression requires too many file descriptors to be opened (1806). Check your
         system limits or install the posix extension to allow Box to automatically configure it during the compression

This is the first time ever I got it... 1806 matches the number of files found in box.phar, but what looks weird is that:

posix_getrlimit()['soft openfiles'] => 10240
posix_getrlimit()['hard openfiles'] => 10240

So it is likely that either checking this file limit is not enough...

For the record, the limit is bumped here and the actual code for bumping the limit is here

This issue is still occurring locally... no clue why or how to fix it
