Description
Description of the problem or steps to reproduce
Sometimes micro gets stuck when trying to open a file (nothing get displayed, just a blank screen), even with a small file (in latest case 983 bytes).
strace shows it stuck on futex(ADDRESS, FUTEX_WAIT_PRIVATE, 0, NULL)
In any case where micro is stuck like this, nano has no problem opening the file.
When micro failed today, chromium froze too but was fine on restarting the browser, whereas I don't know how to unstuck micro, usually I restart the OS but this time it worked fine 20 minutes later..
This problem may be similar to #1818 .

Research direction
Start by reproducing the blank-screen hang while opening a small file on the reported micro version and Arch Linux environment, using strace to confirm the FUTEX_WAIT_PRIVATE wait. Compare the symptoms with issue #1818 and determine what distinguishes micro from nano; done means the hang is explained and no longer occurs in the reported scenario.
